Exodo  30, 13-12

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