Deuteronomy 15:19-21

New Revised Standard Version, Anglicised

The Firstborn of Livestock

¹⁹ Every firstling male born of your herd and flock you shall consecrate to the Lord your God; you shall not do work with your firstling ox nor shear the firstling of your flock. ²⁰ You shall eat it, you together with your household, in the presence of the Lord your God year by year at the place that the Lord will choose. ²¹ But if it has any defect—any serious defect, such as lameness or blindness—you shall not sacrifice it to the Lord your God;
