'Shekels of Silver' in the Bible

If a soul shall commit a trespass, and sin through ignorance, in the holy things of the LORD; then he shall bring for his trespass to the LORD a ram without blemish out of the flocks, with thy estimation by shekels of silver, after the shekel of the sanctuary, for a trespass-offering:

And thy estimation shall be, of the male from twenty years old even to sixty years old, even thy estimation shall be fifty shekels of silver, after the shekel of the sanctuary.

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

And if a man shall sanctify to the LORD some part of a field of his possession, then thy estimation shall be according to the seed of it: a homer of barley seed shall be valued at fifty shekels of silver.
