Deuteronomy 15:17-19

New Century Version

¹⁷ stick an awl^[a] through his ear into the door; he will be your slave for life. Also do this to a female slave.

¹⁸ Do not think of it as a hard thing when you let your slaves go free. After all, they served you six years and did twice the work of a hired person. The Lord your God will bless you in everything you do.

Rules About Firstborn Animals

¹⁹ Save all the first male animals born to your herds and flocks. They are for the Lord your God. Do not work the first calf born to your oxen, and do not cut off the wool from the first lamb born to your sheep.
