for all the firstborn are mine. On the day that I struck down all the firstborn in the land of Egypt I made holy to me all the firstborn in Yisra'el, both man and animal. They shall be mine. I am the LORD.*
All the firstborn males that are born of your herd and of your flock you shall sanctify to the LORD your God: you shall do no work with the firstborn of your herd, nor shear the firstborn of your flock.
