Exodus 30:12-13 ▼

12 “When you take a census of the sons of Israel to number them, then each one of them shall give a price of atonement for himself to Yahweh when you number them, so that there will be no plague among them when you number them.

13 This is what everyone who is numbered shall give: half a shekel according to the shekel of the sanctuary (the shekel is twenty gerahs), half a shekel as a contribution to Yahweh.
