Everyone who is registered must pay half a shekel according to the sanctuary shekel (20 gerahs to the shekel). This half shekel is a contribution to the Lord.

All your valuations shall be according to the shekel of the sanctuary: twenty gerahs to the shekel.

Thou shalt even take five shekels apiece by the poll, after the shekel of the sanctuary shalt thou take them: (the shekel is twenty gerahs:)

And those that are to be redeemed from a month old you shall redeem, according to your judgment for the silver of five shekels, according to the shekel of the sanctuary, which is twenty gerahs.

And the shekel shall be twenty gerahs: twenty shekels, five and twenty shekels, fifteen shekels, shall be your maneh.
