Deuteronomy 15:19

19Set 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.

19“You shall consecrate to the Lord your God all the firstborn males that are born in your herd and in your flock; you shall not work with the firstborn of your herd, nor shear the firstborn of your flock.

19“You shall consecrate to the Lord your God all the firstborn males that are born of your herd and of your flock; you shall not work with the firstborn of your herd, nor shear the firstborn of your flock.

19“You shall consecrate (set apart) to the Lord your God all the firstborn males that are born of your herd and flock. You shall not work with the firstborn of your herd, nor shear the firstborn of your flock.

19You must set apart to the Lord your God every firstborn male produced by your herds and flocks. You are not to put the firstborn of your oxen to work, nor are you to shear the firstborn of your flock.

19Set apart every male animal among your livestock that was born first to its mother. Set it apart to the Lord your God. Don’t put a firstborn cow to work. Don’t clip the wool from a firstborn sheep.
