You shall redeem those who are to be redeemed of them from a month old, according to your estimation, for five shekels of money, according to the shekel of the sanctuary, which weighs twenty gerahs.
“But you shall not redeem the firstborn of a cow, or the firstborn of a sheep, or the firstborn of a goat.
They are holy.
You shall sprinkle their blood on the altar, and shall burn their fat for an offering made by fire, for a pleasant aroma to the LORD.
Their meat shall be yours, as the wave offering breast and as the right thigh, it shall be yours.
