Exodus 22:31 BBE

²⁹  Do not keep back your offerings from the wealth of your grain and your vines. The first of your sons you are to give to me.

³⁰  In the same way with your oxen and your sheep: for seven days let the young one be with its mother; on the eighth day give it to me.

³¹  You are to be holy men to me: the flesh of no animal whose death has been caused by the beasts of the field may be used for your food; it is to be given to the dogs.
