Deuteronomy 15:18-20 Tree of Life Version (TLV)
18 It should not seem hard to you when you set him free from you, for he has served you six years—double the value of a hired worker. So Adonai your God will bless you in all that you do.
19 “All the firstborn males that are born in your herd and your flock you are to consecrate to Adonai your God. You are to do no work with the firstborn of your herd or shear the firstborn of your flock. 20 You are to eat it before Adonai your God year after year in the place Adonai chooses—you and your household.
