Exodus 30:11-16
11 Offerings for the TentThe LORD told Moses,
12 “When you take a census of the Israelis to register them, each is to give a ransom for himself to the LORD when they’re registered so there won’t be a plague among them when they’re registered.
13 This is what everyone who is registered is to give: half a shekel according to the shekel of the sanctuary (the shekel weighs 20 gerahs), half a shekel as a contribution to the LORD.
14 All who are registered, 20 years of age and older, are to give a contribution to the LORD.
15 The rich person is not to give more, nor is the poor person to give less than the half shekel, when you give a contribution to the LORD to make atonement for yourselves.
16 You are to take the atonement money from the Israelis and give it for the service of the Tent of Meeting, and it is to be a memorial for the Israelis in the LORD’s presence to make atonement for yourselves.”
