'Womb' in the Bible

The Lord said to her,“[The founders of] two nations are in your womb;And the separation of two nations has begun in your body;The one people shall be stronger than the other;And the older shall serve the younger.”

When her days to be delivered were fulfilled, behold, there were twins in her womb.

Now when the time came for her to give birth, there were twins in her womb.

By the God of your father who will help you,And by the Almighty who blesses youWith blessings of the heavens above,Blessings lying in the deep that couches beneath,Blessings of the [nursing] breasts and of the [fertile] womb.
