Exodus 30:13-15

New Revised Standard Version, Anglicised Catholic Edition

¹³ This is what each one who is registered shall give: half a shekel according to the shekel of the sanctuary (the shekel is twenty gerahs), half a shekel as an offering to the Lord. ¹⁴ Each one who is registered, from twenty years old and upwards, shall give the Lord’s offering. ¹⁵ The rich shall not give more, and the poor shall not give less, than the half-shekel, when you bring this offering to the Lord to make atonement for your lives.
