'Shekels of Silver' in the Bible

If a soul commits a trespass, and sins through ignorance, in the holy things of the LORD; then he shall bring for his trespass unto the LORD a ram without blemish out of the flocks, with your valuation by shekels of silver, after the shekel of the sanctuary, for a trespass offering:

Then your valuation shall be for the male from twenty years old even unto sixty years old, even your valuation shall be fifty shekels of silver, after the shekel of the sanctuary.

And if it be from a month old even unto five years old, then your valuation shall be for the male five shekels of silver, and for the female your valuation shall be three shekels of silver.

And if a man shall dedicate unto the LORD some part of a field of his possession, then your valuation shall be according to the seed from it: a homer of barley seed shall be valued at fifty shekels of silver.
