Shemot 34:18-20

Orthodox Jewish Bible

¹⁸ The Chag Hamatzot shalt thou be shomer over. Shivat yamim thou shalt eat matzot, as I commanded thee, in the mo’ed of the month Aviv; for in the month Aviv thou camest out from Mitzrayim.

¹⁹ All that openeth the rechem (womb) is Mine; and every firstling among thy cattle, whether ox or seh, that is zachar.

²⁰ But the firstling of a donkey thou shalt redeem with a seh; and if thou redeem him not, then shalt thou break his neck. Kol bechor of thy banim thou shalt redeem. And none shall appear before Me empty.
