Deuteronomy 15:18-20

New Catholic Bible

¹⁸ Do not consider it to be a hardship to set your slave free. You received twice as much from him in the six years as you would have from a hired hand, and the Lord, your God, will bless you in all of your undertakings.

¹⁹ The Firstborn. Set apart for the Lord, your God, the firstborn male from your herds and your flocks. Do not set the firstborn of your oxen to work, nor shear the firstborn of your sheep. ²⁰ Each year you and your family are to eat them before the Lord, your God, in the place that the Lord has chosen.
