Exodus 34:18-20

New American Standard Bible

¹⁸ “You shall keep ^(A)the Feast of Unleavened Bread. For ^(B)seven days you are to eat unleavened bread, ^[a]as I commanded you, at the appointed time in the ^(C)month of Abib; for in the month of Abib you came out of Egypt.

¹⁹ “^(D)The ^[b]firstborn from every womb belongs to Me, and all your male livestock, the ^[c]firstborn from ^[d]cattle and sheep. ^20 (E)You shall redeem with a lamb the firstborn from a donkey; and if you do not redeem it, then you shall break its neck. You shall redeem ^(F)all the firstborn of your sons. ^[e](G)None are to appear before Me empty-handed.
