Let the first male child of every mother among the children of Israel be kept holy for me, even the first male birth among man or beast; for it is mine.
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.
But no such payment may be made for the first birth of an ox or a sheep or a goat; these are holy: their blood is to be dropped on the altar, and their fat burned for an offering made by fire, a sweet smell to the Lord.
All the first males to come to birth in your herd and your flock are to be holy to the Lord your God: the first birth of your ox is not to be used for work, the wool of your first lamb is not to be cut.
