Deuteronomy 15:18-20 1599 Geneva Bible (GNV)
18 Let it not grieve thee, when thou lettest him go out free from thee: for he hath served thee six years, which is the double worth of [a]an hired servant: and the Lord thy God shall bless thee in all that thou doest.
19 ¶ All the firstborn males that come of thy cattle, and of thy sheep, thou shalt sanctify unto the Lord thy God. [b]Thou shalt do no work with thy firstborn bullock, nor shear thy firstborn sheep.
20 Thou shalt eat it before the Lord thy God year by year, in the place which the Lord shall choose, both thou, and thine household.
Deuteronomy 15:18-20 New International Version (NIV)
18 Do not consider it a hardship to set your servant free, because their service to you these six years has been worth twice as much as that of a hired hand. And the Lord your God will bless you in everything you do.
The Firstborn Animals
19 Set apart for the Lord your God every firstborn male of your herds and flocks. Do not put the firstborn of your cows to work, and do not shear the firstborn of your sheep. 20 Each year you and your family are to eat them in the presence of the Lord your God at the place he will choose.
