Deuteronomy 15:18-20

Modern English Version

¹⁸ It will not seem difficult for you when you send him away free from you, for he has been worth a double hired servant^[a] in serving you six years. Then the Lord your God will bless you in all that you do.

The Firstborn Animals

¹⁹ You must sanctify all the firstborn males that come out of your herd and flock to the Lord your God. You must do no work with the firstborn of your bulls or shear the firstborn of your sheep. ²⁰ You shall eat it before the Lord your God year by year in the place where the Lord shall choose, you and your household.
