'Silver' in the Bible

If any one commit a trespass, and sin unwittingly, in the holy things of Jehovah; then he shall bring his trespass-offering unto Jehovah, a ram without blemish out of the flock, according to thy estimation in silver by shekels, after the shekel of the sanctuary, for a trespass-offering:

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 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 a man shall sanctify unto Jehovah part of the field of his possession, then thy estimation shall be according to the sowing thereof: the sowing of a homer of barley'shall be valued at fifty shekels of silver.
