'Exchange' in the Bible

Let your exchange of goods with your neighbours have relation to the number of years after the year of Jubilee, and the number of times the earth has given her produce.

No exchange of land may be for ever, for the land is mine, and you are as my guests, living with me for a time.

But nothing which a man has given completely to the Lord, out of all his property, of man or beast, or of the land which is his heritage, may be given away or got back in exchange for money; anything completely given is most holy to the Lord.

He may not make search to see if it is good or bad, or make any changes in it; and if he makes exchange of it for another, the two will be holy; he will not get them back again.
