Shemot 34:17-19

Orthodox Jewish Bible

¹⁷ Thou shalt make thee no elohei massekhah.

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.
