'Shekel' in the Bible

If any one act unfaithfully and sin through inadvertence in the holy things of Jehovah, then he shall bring his trespass-offering to Jehovah, a ram without blemish out of the small cattle, according to thy valuation by shekels of silver, according to the shekel of the sanctuary, for a trespass-offering.

And thy valuation shall be of the male from twenty years old even unto sixty years old: thy valuation shall be fifty shekels of silver, after the shekel of the sanctuary;

And all thy valuation shall be according to the shekel of the sanctuary: twenty gerahs shall be the shekel.
