'Estimated' in the Bible

"When a person commits a truly treacherous act and sins inadvertently concerning the sacred things of the LORD, then he is to bring a trespass offering to the LORD from the flock as compensation for his guilt. It is to be a ram without defect, estimated as to its value in silver shekels, according to the sanctuary shekel.

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.

Now as to his guilt offering, he is to bring to the LORD a ram without defect from the flock, estimated as to its value, to the priest.
