Shemot 34:19-21

Orthodox Jewish Bible

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.

²¹ Sheshet yamim thou shalt work, but on the yom hashevi’i thou shalt rest; in plowing and in harvest thou shalt rest.
