'Number' in the Bible

unto the morrow of the seventh sabbath ye do number fifty days, and ye have brought near a new present to Jehovah;

by the number of years after the jubilee thou dost buy from thy fellow; by the number of the years of increase he doth sell to thee;

according to the multitude of the years thou dost multiply its price, and according to the fewness of the years thou dost diminish its price; for a number of increases he is selling to thee;

'And he hath reckoned with his buyer from the year of his being sold to him till the year of jubilee, and the money of his sale hath been by the number of years; as the days of an hireling it is with him.
