Numbers 3:46-48

Young's Literal Translation

⁴⁶ `And [from] those ransomed of the two hundred and seventy and three (who are more than the Levites) of the first-born of the sons of Israel,

⁴⁷ thou hast even taken five shekels a-piece by the poll -- by the shekel of the sanctuary thou takest; twenty gerahs the shekel [is];

⁴⁸ and thou hast given the money to Aaron, and to his sons, whereby those over and above are ransomed.'
