Exodus 30:15-16 ▼

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.”
