26Only the firstling among beasts, which is made a firstling to Jehovah, no man shall sanctify it; whether it be ox or sheep, it is Jehovah`s. 27And if it be of an unclean beast, then he shall ransom it according to thine estimation, and shall add unto it the fifth part thereof: or if it be not redeemed, then it shall be sold according to thy estimation.
Leviticus 27:26-27 (ASV)
