'Redeem' in the Bible

All [the] first offspring of a womb of any creature that they offer to Yahweh, whether human or animal, will be yours; you will surely redeem the firstborn of the human and the unclean firstborn of the animal.

As to their price of redemption, from {a one-month-old} you will redeem them according to your proper value, five shekels of silver according to the shekel of the sanctuary, which [is] twenty gerah.

Only the firstborn of an ox or the firstborn of a sheep or the firstborn of a goat you will not redeem; they [are] holy. Their blood you will sprinkle over the altar, and their fat you will turn into smoke [as] an offering made by fire, a fragrance of appeasement for Yahweh.
