'Womb' in the Bible

“Sanctify to Me every firstborn, the first offspring of every womb among the sons of Israel, both of man and beast; it belongs to Me.”

you shall devote to the Lord the first offspring of every womb, and the first offspring of every beast that you own; the males belong to the Lord.

It came about, when Pharaoh was stubborn about letting us go, that the Lord killed every firstborn in the land of Egypt, both the firstborn of man and the firstborn of beast. Therefore, I sacrifice to the Lord the males, the first offspring of every womb, but every firstborn of my sons I redeem.’

“The first offspring from every womb belongs to Me, and all your male livestock, the first offspring from cattle and sheep.
