“Do not hold back offerings from your granaries or your vats. You must give me the firstborn of your sons.

“Every firstborn of the womb belongs to me, even every firstborn of your cattle that is a male, whether ox or sheep.

because all the firstborn are mine. When I destroyed all the firstborn in the land of Egypt, I set apart for myself all the firstborn in Israel, both man and beast. They belong to me. I am the LORD.”
