Exodus 34:19-21

Amplified Bible, Classic Edition

¹⁹ All the males that first open the womb among your livestock are Mine, whether ox or sheep.

²⁰ But the firstling of a donkey [an unclean beast] you shall redeem with a lamb or kid, and if you do not redeem it, then you shall break its neck. All the firstborn of your sons you shall redeem. And none of you shall appear before Me empty-handed.

²¹ Six days you shall work, but on the seventh day you shall rest; even in plowing time and in harvest you shall rest [on the Sabbath].
