Exodus 30:14

¹²If thou take account of the children of Israel in the surveying of them, and they shall give every one a ransom for his soul to the Lord, then there shall not be among them a destruction in the visiting of them.

¹³And this is what they shall give, as many as pass the survey, half a didrachma which is according to the didrachma of the sanctuary: twenty oboli go to the didrachma, but the half of the didrachma is the offering to the Lord.

— Exodus 30:14 —

¹⁵The rich shall not give more, and the poor shall not give less than the half didrachma in giving the offering to the Lord, to make atonement for your souls.

¹⁶And thou shalt take the money of the offering from the children of Israel, and shalt give it for the service of the tabernacle of testimony; and it shall be to the children of Israel a memorial before the Lord, to make atonement for your souls.
