Deuteronomy 15:18-20

Revised Standard Version

¹⁸ It shall not seem hard to you, when you let him go free from you; for at half the cost of a hired servant he has served you six years. So the Lord your God will bless you in all that you do.

The Firstborn of Livestock

¹⁹ “All the firstling males that are born of your herd and flock you shall consecrate to the Lord your God; you shall do no work with the firstling of your herd, nor shear the firstling of your flock. ²⁰ You shall eat it, you and your household, before the Lord your God year by year at the place which the Lord will choose.
