Numbers 3:46-48

New Living Translation

⁴⁶ There are 273 more firstborn sons of Israel than there are Levites. To redeem these extra firstborn sons, ⁴⁷ collect five pieces of silver^[a] for each of them (each piece weighing the same as the sanctuary shekel, which equals twenty gerahs). ⁴⁸ Give the silver to Aaron and his sons as the redemption price for the extra firstborn sons.”
