Gerah

This they shall give, every one that passeth among them that are numbered, half a shekel after the shekel of the sanctuary:(a shekel is twenty gerahs:) an half shekel shall be the offering of the LORD.

And all thy estimations shall be according to the shekel of the sanctuary: twenty gerahs shall be 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:)
