'Number' in the Bible

Corresponding to the number of years after the jubilee, you shall buy from your friend; he is to sell to you according to the number of years of crops.

In proportion to the extent of the years you shall increase its price, and in proportion to the fewness of the years you shall diminish its price, for it is a number of crops he is selling to you.

He then with his purchaser shall calculate from the year when he sold himself to him up to the year of jubilee; and the price of his sale shall correspond to the number of years. It is like the days of a hired man that he shall be with him.

I will let loose among you the beasts of the field, which will bereave you of your children and destroy your cattle and reduce your number so that your roads lie deserted.
