All the firstling males that come of thy herd and of thy flock thou shalt sanctify unto the LORD thy God: thou shalt do no work with the firstling of thy bullock, nor shear the firstling of thy sheep.
All the firstling males ... thou shalt sanctify - (see the note at Exodus 22:30.)
Thou shalt do no work with the firstling of thy bullock - i:e., the second firstlings (see the notes at Deuteronomy 12:17-18; Deuteronomy 14:23).
