Deuteronomy 15:19-20

Rotherham(i) 19 Every firstling that is brought forth in thy herd and in thy flock, that is a male, shalt thou hallow unto Yahweh thy God,––thou shalt not work with a firstling of thine oxen, neither shalt thou shear a firstling of thy flock: 20 before Yahweh thy God, shalt thou eat it, year by year, in the place which Yahweh shall choose,––thou, and thy household.
