'Womb' in the Bible

"Consecrate to me every firstborn, the first offspring of every womb among the {Israelites}, among humans and among domestic animals; {it belongs to me}."

you will hand over every first offspring of a womb to Yahweh, and every first offspring dropped by a domestic animal that will belong to you, the males [will be] for Yahweh.

And when Pharaoh was stubborn to release us, Yahweh killed every firstborn in the land of Egypt, from firstborn human to firstborn domestic animal. Therefore I [am] sacrificing to Yahweh every first offspring of a womb, the males, and every firstborn of my sons I redeem.'

Every first offspring of a womb [is] for me--all of your male livestock, [the] first offspring of cattle and small livestock.
