'Reckon' in the Bible

And he shall reckon with him that bought him from the year that he was sold to him unto the year of jubile: and the price of his sale shall be according unto the number of years, according to the time of an hired servant shall it be with him.

But if he sanctify his field after the jubile, then the priest shall reckon unto him the money according to the years that remain, even unto the year of the jubile, and it shall be abated from thy estimation.

Then the priest shall reckon unto him the worth of thy estimation, even unto the year of the jubile: and he shall give thine estimation in that day, as a holy thing unto the LORD.
