'Reckon' in the Bible

then shall he reckon the years since the sale thereof, and restore the overplus unto the man to whom he sold it; and so return unto his possession.

And he shall reckon with him that bought him from the year that he was sold to him unto the year of jubilee; and the price of his sale shall be according to the number of the years, according to the days of a hired servant shall he be with him.

and if there remain but few years unto the year of jubilee, then he shall reckon with him; according unto his remaining years of service shall he give him back his redemption money.

but if he hallow his field after the jubilee, then the priest shall reckon unto him the money according to the years that remain, until the year of the jubilee; and there shall be a reduction from thy valuation.

the priest shall reckon unto him the amount of thy valuation, unto the year of the jubilee; and he shall give thy valuation on that day, as holy to Jehovah.
