Exodus 34:16

12Take heed to thyself, lest thou make a covenant with the inhabitants of the land whither thou goest, lest it be for a snare in the midst of thee:

13But ye shall destroy their altars, break their images, and cut down their groves:

14For thou shalt worship no other god: for the Lord, whose name is Jealous, is a jealous God:

15Lest thou make a covenant with the inhabitants of the land, and they go a whoring after their gods, and do sacrifice unto their gods, and one call thee, and thou eat of his sacrifice;

16And thou take of their daughters unto thy sons, and their daughters go a whoring after their gods, and make thy sons go a whoring after their gods.

17Thou shalt make thee no molten gods.

18The feast of unleavened bread shalt thou keep. Seven days thou shalt eat unleavened bread, as I commanded thee, in the time of the month Abib: for in the month Abib thou camest out from Egypt.

19All that openeth the matrix is mine; and every firstling among thy cattle, whether ox or sheep, that is male.

20But the firstling of an ass thou shalt redeem with a lamb: and if thou redeem him not, then shalt thou break his neck. All the firstborn of thy sons thou shalt redeem. And none shall appear before me empty.
