'Selling' in the Bible

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.

then he shall calculate the years of its selling, and he shall refund the balance to the man to whom he sold [it], and he shall return to his property.

And when a man selleth a dwelling-house in a walled city, then hath his right of redemption been until the completion of a year from its selling; days -- is his right of redemption;

And whatever [anyone] redeems from the Levites then must go out [of the buyer's hand] in the Jubilee, [including] a house's selling {in his city's property}, because the houses in the cities of the Levites [are] their property in the midst of the {Israelites}.

And he shall calculate with his buyer from the year of {his selling himself} until the Jubilee; and the value of his selling shall be according to the number of years--it shall be with him like a hired worker's days.
