When they are one month old you shall pay the redemption price of five shekels of silver (using the sanctuary shekel standard), equivalent to twenty gerahs.
Each one who crosses over to those counted must give a half shekel (using the sanctuary shekel standard, which weighs twenty gerahs). This half shekel is an offering to the Lord.
The total amount of gold from the offering that was used for the work on the sanctuary was 29 talents and 730 shekels (using the sanctuary shekel standard).
Every firstborn, whether human or animal, that is offered to the Lord is yours. But you must buy back every firstborn son and every firstborn male of unclean animals.
But you are not allowed to redeem the firstborn of an ox, a sheep, or a goat because they are holy. You shall sprinkle their blood on the altar, and burn their fat as a burnt offering accepted by the Lord.
