'Shekels' in the Bible

If a soul commit a trespass, and sin 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 thy estimation by shekels of silver, after the shekel of the sanctuary, for a trespass offering:

He is to bring from the flock to the priest a ram without defect, estimated as to its value in silver shekels, as a guilt offering. Then the priest is to make atonement for him concerning his inadvertent act that he committed through ignorance, and it will be forgiven him.

Then he must bring his guilt offering to the Lord, a flawless ram from the flock, convertible into silver shekels, for a guilt offering to the priest.

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

And if it be a female, then thy estimation shall be thirty shekels.

And if it be from five years old even unto twenty years old, then thy estimation shall be of the male twenty shekels, and for the female ten shekels.

And if it be from a month old even unto 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 it be from sixty years old and above; if it be a male, then thy estimation shall be fifteen shekels, and for the female ten shekels.

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