'Number' in the Bible

You are to make the purchase from your neighbor based on the number of years since the last Jubilee. He is to sell to you based on the number of remaining harvest years.

You are to increase its price in proportion to a greater amount of years, and decrease its price in proportion to a lesser amount of years, because what he is selling to you is a number of harvests.

The one who purchased him is to calculate the time from the year he sold himself to him until the Year of Jubilee. The price of his sale will be determined by the number of years. It will be set for him like the daily wages of a hired hand.
