Of the firstlings, that come of thy herds and thy sheep, thou shalt sanctify to the Lord thy God whatsoever is of the male sex. Thou shalt not work with the firstling of a bullock: and thou shalt not shear the firstlings of thy sheep.
But the firstling of a cow and of a sheep and of a goat thou shalt not cause to be redeemed, because they are sanctified to the Lord. Their blood only thou shalt pour upon the altar: and their fat thou shalt burn for a most sweet odour to the Lord.
And if it be an unclean beast, he that offereth it shall redeem it, according to thy estimation, and shall add the fifth part of the price. If he will not redeem it, it shall be sold to another for how much soever it was estimated by thee.
For every firstborn is mine. Since I struck the firstborn in the land of Egypt, I have sanctified to myself whatsoever is firstborn in Israel both of man and beast. They are mine. I am the Lord.
And the firstborn of our sons, and of our cattle, as it is written in the law, and the firstlings of our oxen, and of our sheep, to be offered in the house of our God, to the priests who minister in the house of our God.
