There is also a Bethulah Pregnancy in The Hebrew Bible.

The Prophets of Ancient Israel refereed often to The Daughter of Zion.

In 2 Kings 19:22, Isaiah 37:22 and Lamentations 2:13 she is explicitly refereed to as a Bethulah, translated Virgin in the KJV.

But in Jeremiah 4:21 and Micah 4:10 she travails in childbirth.

Jeremiah specifically says both things.

So I've shown in the past that Almah implies Virginity, and I've shown that other objections to viewing Isaiah 7-8 as Messianic don't hold up.  And now I've shown that there is an implied Bethulah Birth in Bible Prophecy as well.

So make no mistake, The Virgin Birth is rooted in The Hebrew Bible.
