The Virgin Birth

[Chomsky]

Jesus' birth in Isaiah 7:14 states: "Therefore the Lord himself will give you a sign: The virgin will conceive and give birth to a son, and will call him Immanuel."
The Hebrew "almah" means "young woman" and not a "virgin." However, the Greek Septuagint translated it as "parthenos" (virgin), and the Gospel of Matthew uses this translation to link the prophecy to Jesus.
Would someone help me understand why this happened?

Correct the term is "almah"

Ge 24:43 Behold, I stand by the well of water; and it shall come to pass, that when the virgin cometh forth to draw water, and I say to her, Give me, I pray thee, a little water of thy pitcher to drink;
44 And she say to me, Both drink thou, and I will also draw for thy camels: let the same be the woman whom the LORD hath appointed out for my master's son.
45 And before I had done speaking in mine heart, behold, Rebekah came forth with her pitcher on her shoulder;

Rebekah is a young woman past puberty and un married - so she is a virgin - all marriages required a blood token to make the marriage true - hence the woman had to be sealed for this to happen.

Ex 2:8 And Pharaoh's daughter said to her, Go. And the maid went and called the child's mother.

Here the same term can refer to a young woman from 12 years to 20 years.

Hope this helps
