The Messianic Prophecy, my Jewish Friend, Part Two

How was Israel going to recognize the Messiah?

Miraculous birth in Isaiah 7:14
The word in Isiah 7:14 is Almah. Almah means A Lass (as veiled or private), Damsel, Maid, Virgin, Concealment, Unmarried female, Young woman, Strong's Concordance Dictionary, page 89. Young's Concordance, page 1026.

Septuagint: Old Testament Translated into Greek. Translated by 70 Jewish scholars about 300 B.C. Isiah 7:14, Almah=Parthenos=Virgin.

The word used for "sign" is Oat, "sign, a signal as a flag, beacon, monument, omen, evidence, mark, miracle, token" Strong's Concordance, page 10.

Hezekiah's sign- "Oat"- the sun going back 10 degrees: 2 Kings 20:1-11; Moses "signs" in Egypt: Exodus 4:8, 8, 9, 17, 28, 30; 7:3; 8:23; 10:1,2; 12:13; 13:9, 16.

Cyrus Gordon, a leading Jewish scholar who was formerly Professor of Assyriology and Egyptology, Dropsie College, wrote" "The commonly held view that "virgin" is Christian, whereas "young woman" is Jewish is not quite true. The fact is that the Septuagint, which is the Jewish translation of the Old Testament, made in pre-Christian Alexandria, takes 'almah' to mean "virgin" here. Accordingly the New Testament follows Jewish interpretation in Isiah 7:14. "From Ugarit of around 1400 B.C. comes a text celebrating the marriage of the male and female lunar deities. It is there predicted that the goddess will bear a son... The terminology is remarkably close to that in Isaiah 7:14. However, the Ugaritic statement that the bride will bear a son is fortunately given in parallelistic form; in 77:7 she is called by the exact etymological counterpart of Hebrew 'almah' "young woman"; in 77:5 she is called by the exact etymological counterpart of Hebrew betulah "virgin". Therefore, the New Testament rendering of 'almah' as "virgin" for Isaiah 7:14 rests on the older Jewish interpreation, which in turn is now borne out for precisely  this annunciation formula by a text that is not only pre-Isaianic but is pre-Mosaic in the form that we now have it on a clay tablet.

Jewish sages have sometimes had sometimes had something to say about the possibility of a virgin birth:

Abraham Farissol, medieval Jewish sage:
"We cannot deny the possibility that God, may He be blessed, could create in a virgin, even one whom no man has known, for He created everything out of nothing."
- quoted by Daniel J. Lasker, Jewish Philosophical Polemics Against Christianity in the Middle Ages (New York: KTAV/ADL, 1977), page 153.

People will fight against the Virgin birth but the proof is shows the evidence for the Virgin birth.
