Exodus 30:14-16

Amplified Bible

¹⁴ Everyone who is counted, from twenty years old and over, [as he joins those already counted], shall give this contribution to the Lord.^{(A) 15} The rich shall not give more and the poor shall not give less than half a shekel, when you give this contribution to the Lord to make atonement for yourselves. ¹⁶ You shall take the atonement money from the Israelites and use it [exclusively] for the service of the Tent of Meeting, so that it may be a memorial for the Israelites before the Lord, to make atonement for yourselves.”
