This is what everyone passing over to be numbered shall give: half a shekel according to the shekel of the sanctuary (a shekel is twenty gerahs). The half-shekel shall be an offering unto Jehovah.

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

you shall take five shekels per head; you shall take them according to the shekel of the sanctuary, the shekel of twenty gerahs.
