The letter VAV is the second letter in creation, it comes from the letter Yod, which is the soul of HaShem, is given to man, whom stretches it down to this earth, thus connecting Ben Adam (human beings) to the heavens. Its numerical value is six.

In the Hebrew Alef Beit the letter VAV is the sixth letter of the Hebrew alphabet is called "VAV" (pronounced "VAV") and has the sound of "v" as in "vine."

The numeric value of the letter VAV is six. The pictograph for VAV looks like a tent peg (or a man standing), whereas the classical Hebrew script (ketav Ashurit / Assyrian lettering) is constructed of a vertical line and conjoined Yod. The meaning of the word VAV is "hook," as a connecting hook used when the Mishkan (tabernacle) was assembled.

According to Jewish tradition as we said, the letter VAV is an extended Yod. As such, it’s the letter that represents drawing down the Yod of HaShem’s name (Yod also represents Divine wisdom, the source of Torah) into this world. The letter VAV is the connection between heaven and earth. Also, the VAV connects time past and future.

Six also represents completion, because something that is surrounded on all six sides—north, south, east, west, above and below—is complete.

Additionally The VAV represents the Torah because the word Yisrael, is an acronym meaning “There are six hundred thousand letters of the Torah,” and if one letter of the Torah is missing or broken or cracked, HaShem forbid, the entire Torah scroll is declared not kosher—unfit to be read.

The world was created in six days—the Six Days of Creation. The first word in the Torah is Bereshit (“In the beginning”) which itself is composed of six letters, בראשית. Furthermore the Torah clearly states: “G-d created in six days.”

There are also six Alef (the first letter in the Hebrew Alef-beit) in the first verse of the Torah. The first VAV in the Torah is found at the beginning of the sixth word (v’et). So Creation is connected to the number six.

Genesis 1:1: Bereshit bara Elokim et hashamayim ve’et ha’arets.

The letter VAV and Mashiach (King Messiah who brings teachings from heaven to earth). As explained in Jewish tradition, Adam is the prototype of Mashiach, who is the perfect man. The word “Adam” is spelled אדם.The Alef (gematria one) represents intellect, the first of a person’s ten faculties. Dalet, the second letter of Adam, is the first letter of dibbur, or speech. Mem signifies maaseh, action. Thus the second Adam, or Mashiach, will be perfect in his thought, speech, and action.

Hebrew Torah Factoid:

The Belly of the Torah; an oversized VAV marks the "center" of the entire Torah (Leviticus 11:42): "Whatsoever goes upon the BELLY,…" Appropriately enough, the word in which this VAV occurs is gachon, meaning "belly."

This enlarged letter provides the scribe with an heuristic device to insure that there are precisely 152,402 letters before this “vav” (the name of the letter), and 152,402 letters after this “vav.”

You might say, “Fascinating. But, so what? Hebrews consider the very letters of the Scripture inspired. That means that every letter carries the breath of God. None are accidental. None are trivial.

Other uses for the letter VAV. The VAV is a picture of Man.  Man was created on the sixth day. Man works for six days – the realm of the mundane.  There are six millennia before the full revelation of the Mashiach. Six, is the number of labor, man’s labor is apart and distinct from HaShem’s commanded rest. The Sixth Commandment relates to the worst sin – murder (which refers to kidnapping a human being). A Hebrew slave was to serve 6 years and be released in the 7th year.  Six years were appointed for the land to be sown and harvested. The letter VAV is used at the beginning of Hebrew years, it means 6000 (i.e. ותשנד in numbers would be the date 6754 for example.)

On a syntactic level, adding a VAV to the beginning of any word creates the meaning “and”; for example, v’eileh means “and these things.” Within a sentence, “and” is the hook that connects one word or clause to the next. Furthermore, the VAV attached to a verb converts that verb from either the past to the future tense, or from the future to the past tense. For example, the word haya in Hebrew means “it was.” The word v’haya means “it will be.” By merely attaching the VAV, the past is transformed into the future. In reverse, consider the word yehi, which means “it shall be,” as in “Yehi or [And G-d said,] “Let there be light.” Place a VAV in front—vayehi—and the meaning becomes, “There was light,” in the past tense.

When placed in front of a verb in the perfect, it changes the verb to the imperfect tense. For example, ahavtah means ‘you loved’, and ve’ahavtah means ‘you will love’.
