'Redemption' in the Bible

For the redemption of the two hundred seventy-three of the firstborn of the children of Israel, who exceed the number of the Levites,

Moses took the redemption money from those who exceeded the number of those who were redeemed by the Levites;

and Moses gave the redemption money to Aaron and to his sons, according to the word of Yahweh, as Yahweh commanded Moses.
