Deuteronomy 15:18-20 New Life Version (NLV)
18 It should not be hard for you to set him free for he has worked for you six years. He has been worth twice as much as a man paid to work for you. The Lord your God will bring good to you in whatever you do.
19 “Set apart for the Lord your God all the first-born males among your cattle and your flock. Do no work with the first-born of your cattle. Do not cut the wool from the first-born of your flock. 20 You and those of your house will eat it every year before the Lord your God in the place the Lord chooses.
