Deuteronomy 15:19-21

Living Bible

¹⁹ “You shall set aside for God all the firstborn males from your flocks and herds. Do not use the firstborn of your herds to work your fields, and do not shear the firstborn of your flocks of sheep and goats. ²⁰ Instead, you and your family shall eat these animals before the Lord your God each year at his sanctuary. ²¹ However, if this firstborn animal has any defect such as being lame or blind, or if anything else is wrong with it, you shall not sacrifice it.
