Exodus 34:18-20

New Catholic Bible

¹⁸ “Observe the Feast of Unleavened Bread. For seven days eat unleavened bread at the appointed time in the month of Abib, for it was in the month of Abib that you came out of Egypt.

¹⁹ “Every creature that is the firstborn from its mother’s womb belongs to me: every firstborn bull, every firstborn cattle and sheep. ²⁰ The firstborn of a donkey will be redeemed with a lamb. If you do not redeem it, you are to break its neck. All of your firstborn sons are to be redeemed.

“None is to appear before me empty-handed.
