“You 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.”
Deuteronomy 15:19 (BSB)
Context Reading
17then take an awl and pierce it through his ear into the door, and he will become your servant for life. And treat your maidservant the same way. 18Do not regard it as a hardship to set your servant free, because his six years of service were worth twice the wages of a hired hand. And the LORD your God will bless you in all you do. 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. 20Each year you and your household are to eat it before the LORD your God in the place the LORD will choose. 21But if an animal has a defect, is lame or blind, or has any serious flaw, you must not sacrifice it to the LORD your God.
