Exodus 22:30

And ye shall be holy men to me; and ye shall not eat flesh taken of beasts, ye shall cast it to the dog.

Likewise shalt thou do with thine oxen, and with thy sheep: seven days it shall be with his dam; on the eighth day thou shalt give it me.

You shall do likewise with your cattle and with your sheep. It shall be with its mother seven days, then on the eighth day you shall give it to me.
