Deuteronomy 15:18-20 Common English Bible (CEB)
18 Don’t consider it a hardship to set these servants free from your service, because they worked for you for six years—at a value double that of a paid worker. The Lord your God will bless you in everything that you do.
19 You must devote every oldest male animal from your herds or flocks to the Lord your God. Don’t plow with your oldest male ox and don’t shear your oldest male sheep. 20 Year after year, you and your family are allowed to eat these animals in the presence of the Lord your God, in the location the Lord selects.
