Exodus 34:18-20

Common English Bible

¹⁸ Observe the Festival of Unleavened Bread. You should eat unleavened bread for seven days, as I commanded you, at the set time in the month of Abib,^[a] because it was in the month of Abib that you came out of Egypt.

¹⁹ Every first offspring is mine. That includes all your male livestock, the oldest offspring of cows and sheep. ²⁰ But a donkey’s oldest offspring you may ransom with a sheep. Or if you don’t ransom it, you must break its neck. You should ransom all of your oldest sons.

No one should appear before me empty-handed.
