Deuteronomy 15:17-19 Expanded Bible (EXB)
17 stick an awl [C a pointed tool for making holes] through his ·ear [earlobe] 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 [Ex. 21:2–6; Lev. 25:39–46].
Rules About Firstborn Animals
19 Save all the first male animals born to your herds and flocks [Ex. 13:2, 11–16; 22:29; Num. 18:15–18]. They are ·for [consecrated to] 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.
