Deuteronomy 15:18-20

New Revised Standard Version Catholic Edition

¹⁸ Do not consider it a hardship when you send them out from you free persons, because for six years they have given you services worth the wages of hired laborers; and the Lord your God will bless you in all that you do.

The Firstborn of Livestock

¹⁹ Every firstling male born of your herd and flock you shall consecrate to the Lord your God; you shall not do work with your firstling ox nor shear the firstling of your flock. ²⁰ You shall eat it, you together with your household, in the presence of the Lord your God year by year at the place that the Lord will choose.
