Hebrew Month:

Isaiah 53 from the Aleppo Codex

Who has believed Our report? And to whom has the arm of יהוה been revealed? For He comes up as a tender plant before Him, and as a Root out of a dry ground. He has no form, nor honor, when we observe Him, nor beauty, that we should desire Him. He was despised, and rejected by men, a man of sorrows, and acquainted with grief. And as one hiding His countenance from us, He was despised, and we did not esteem Him. Surely He has borne our griefs, and carried our sorrows, yet we esteemed Him stricken, smitten by Elohim, and afflicted. And He was pierced for our transgressions, bruised for our iniquities, the punishment that brought us peace was upon Him, and by His stripes we are healed. All we like sheep have gone astray, we have turned each to his own way, and יהוה has laid on Him את the punishment of us all. He was oppressed and He was afflicted, yet He did not open His mouth. He was led as a Lamb to the slaughter, and as a sheep before its shearers is silent, He did not open His mouth. By oppression and trial was taken away, and who can speak of את His descendants? For He was cut off from the land of the living, for the transgressions of My people He was stricken. And He made His grave with את the wicked, and with את the rich in His death, because He had done no violence, nor was any deceit in His mouth. Yet it pleased יהוה to bruise Him and to cause Him to suffer, and though יהוה makes His life an offering for sin, He will see His offspring and prolong His days, and the will of יהוה will prosper in His hand. He shall see the labor of His soul, and be satisfied. By His knowledge My righteous Servant shall justify many, for He shall bear their iniquities. Therefore I will give Him a portion with the great, and shall divide את the spoil with the strong, because He poured out His soul even to death, and was numbered with את the transgressors, and He bore the sin of many, and made intercession for the transgressors.

Determining the Hebrew Month

A Hebrew Month begins at the moment of sunset the evening the moon's crescent first becomes potentially visible to the naked eye in Jerusalem, assuming ideal sighting conditions without smog, haze or clouds. Sightings with the naked eye only occur if the moon appears in the upper left area outlined by the white visibility lines in the sunset diagram below.

Understanding the Sunset Diagram

The diagram above depicts a view of the western sky as seen from the proximity of the Temple Mount in Jerusalem, observed at the moment of sunset, at or near the beginning of a Hebrew Month. Select one of three buttons for viewing the new moon in Jerusalem on either the Day Before, the New Moon Day or the Day After the new moon. Then press the View button.

The darker area at the bottom of the diagram represents a view of the horizon as seen from the observer's location looking toward the west. The yellow circle shows the sun's position just below the horizon at the moment of sunset. The moon is shown as a thin crescent if it is visible. Otherwise, if the moon's center lies on or below the curved part of the white visibility line, it is represented as a white circle. A white circle indicates that the moon's crescent is too faint to be seen with the naked eye due to the overwhelming effect of the evening twilight when the moon is too low in topocentric altitude.

When the crescent moon is located close to the curved white visibility line, it is shown inside a set of cross hairs. In cases like this, the new moon will be barely visible and sighting it will require a perfectly clear sky.

The numbers across the bottom represent the difference in topocentric azimuth (DAZ) between the moon and the sun in degrees. Topocentric azimuth is the angle measured clockwise from true north where due west is 270°. This diagram is not fixed to a particular azimuth. The point on the western horizon where the sun sets is northward in the summer months and more southward during the winter. However, in this diagram, the sunset is framed so that the sun's position is always shown at the same place in the diagram. The actual topocentric azimuth for both the moon and the sun are shown in the tables below. The numbers along the left side of the diagram above show the topocentric altitude angle of the moon (or sun) measured in degrees from the horizon.

If the moon is visible from Jerusalem, it will always lie within the two straight white lines shown in the diagram. The moon never ventures outside of these boundaries because the inclination of the plane of the moon's orbit never exceeds 5.145° with the plane of the earth's mean orbit around the sun known as the ecliptic.

Hebrew Months are numbered consecutively from 1 to 12 in a regular year, or from 1 to 13 in a leap year. The sequence of numbering Hebrew Months in the Creation Calendar is consistent and never changes. Hebrew Month 1 is always at the beginning of a Spiritual Year and occurs at the same time as Hebrew Month 1 in the Civil Year. In this way there will never be confusion about how to keep the appointed times and festivals. Hebrew Months are consistently numbered in an unchanging sequence in the Scriptures.

The Hebrew Months Named in Scripture

In the Hebrew Scriptures written prior to the Babylonian exile, four months are labeled with Canaanite names. The term Aviv describes the agricultural conditions that existed in the month when the Exodus occurred which is equivalent to Month 1. Aviv is a word meaning ripening barley and the month of Aviv is the month of ripening barley (Exodus 13:4, 23:15, 34:18, Deuteronomy 16:1). Ziv was a name for Month 2 which literally means light (1 Kings 6:1, 6:37). Ethanim was a name for Month 7 which literally means strong perhaps referring to strong rains (1 Kings 8:2). Bul was a name for Month 8 (1 Kings 6:38).

In the Hebrew Scriptures written during or after the Babylonian exile, five months appear with Babylonian names. Nisan was a name for Month 1 (Nehemiah 2:1, Esther 3:7). Sivan was a name for Month 3 (Esther 8:9). Elul was a name for Month 6 (Nehemiah 6:15). Kislev was a name for Month 9 (Nehemiah 1:1-2, Zechariah 7:1-3). Adar was a name for Month 12 (Ezra 6:15, Esther 3:7, 3:13, 8:11-12, 9:1, 9:15, 9:17, 9:19, 9:20-22). The name of the pagan deity Tammuz used for Month 4 is mentioned once in Ezekiel 8:14.

It is of great interest to note that the believers who followed  יהושע the Messiah never used pagan names to describe Hebrew Months. They were well taught by the Master and simply numbered the Hebrew Months as Adam and Noah did from the beginning.

The Ancient Paths

The moon is a faithful witness in heaven that  יהוה has firmly established throughout the ages by His word.

Psalms 89:34-37 I will not violate My covenant, nor alter the word that has gone out of My lips. Once I have sworn by My set-apart-ness, I will not lie to David: His seed shall endure throughout the ages, and his throne as the sun before Me. It shall be established throughout the ages like the moon, like the faithful witness in the sky. Selah.

This truth contradicts those who teach that the moon was on a constant cycle of 30 day months, and that a year contained 360 days before the flood. The way in which the Creator reckons time is ultimately demonstrated by the chronology encoded in the history and future prophecy of Scripture.  יהוה instructed Israel to follow the ancient paths or the Creation Calendar.

Jeremiah 6:16 Thus says  יהוה , "Stand in the way and see and ask for the ancient paths, where the good way is, and walk in it, and you shall find rest for your souls."

The good way is also the narrow and precise way spoken of by  יהושע the Messiah.

Matthew 7:13-14 Enter by the narrow gate; for wide is the gate and broad is the way that leads to destruction, and there are many who go in by it. But narrow is the gate and difficult is the way which leads to life, and only a few find it.

Although the Hebrew Hour and the Hebrew Day can be observed from any location on earth, the Hebrew Month and the Hebrew Year must be calculated from near the Temple Mount in Jerusalem. In Hebraic thought, the foundation stone of the Temple of Elohim is considered the origin of the physical universe. It was in the vicinity of the Temple Mount that  יהוה made covenants with Abraham and King David, Solomon built the First Temple, Zerubbabel built the Second Temple, and  יהושע the Messiah renewed the covenant with mankind in His own blood. It is for these reasons that the location of the Temple Mount in Jerusalem is so intrinsically important.

It is first crescent visibility from Jerusalem which is the Scriptural reference standard for time keeping. As Elohim created the lights in heaven for signs, appointed times, days and years (Genesis 1:14), they truthfully tell what time it is. The Scriptures indicate that the Torah of Elohim is truth (Psalms 119:142). They also indicate that the Torah goes forth from Jerusalem.

Isaiah 2:3 And many people shall go and say, Come and let us go up to the mountain of  יהוה , to the house of the Elohim of Jacob; and He will teach us of His ways, and we will walk in His paths: for the Torah will go forth from Zion, and the word of  יהוה from Jerusalem.

For this reason, no one should forget Jerusalem when it comes to sighting the new moon.

Psalms 137:5-6 If I forget you, O Jerusalem, Let my right hand forget its skill! If I do not remember you, Let my tongue cling to the roof of my mouth - If I do not exalt Jerusalem above my chief joy.

In the Age of Life, Jerusalem will be called the City of Truth.

Zechariah 8:3 This is what  יהוה says: "I will return to Zion and dwell in Jerusalem. Then Jerusalem will be called the City of Truth, and the mountain of  יהוה Almighty will be called the Set Apart Mountain."

The new moon and the Sabbath figure prominently in the Age of Life.

Isaiah 66:22-24 "As the new heavens and the new earth that I make will endure before Me," declares  יהוה , "So will your name and descendants endure. From one new moon to another and from one Sabbath to another, all mankind will come and bow down before Me," says  יהוה .

Reckoning the renewed first visible crescent moon from Jerusalem is a highly spiritual act, as it directly connects a person with heaven, and thereby with one's Creator. The heavenly bodies are out of the domain of mankind to control. When a person reckons the beginning of a month by sighting the first visible crescent moon from Jerusalem, that person comes into alignment with the Creator of the universe.

There is not a court on earth that will successfully reject the witness of heaven. The cycles of the moon are one way the Creator communicates with His people. There are many man-made religious systems that operate on calendars that do not take the cycles of the moon into account. However, the heavens will always declare the brilliant majesty of  יהוה who is the Creator of the universe.

Psalms 19:1-6 The heavens declare the brilliant majesty of Elohim and the firmament shows His handywork. Day after day they constantly pour forth speech, and night after night they display intelligence. There is no speech or language where their voice is not heard. Their line is gone out through all the earth and their words to the end of the world. In them He has set a tabernacle for the sun which is as a Bridegroom coming out of His chamber, as a champion rejoices to run a race. It rises at one end of heaven and makes its circuit to the other: nothing is hidden from its heat.

Psalms 97:6 The heavens declare His righteousness, and all the people see His brilliant majesty.
