'Exchanged' in the Bible
And if a Levite does not give money to get back his property, his house in the town which was exchanged for money will come back to him in the year of Jubilee. For the houses of the towns of the Levites are their property among the children of Israel.
But the land on the outskirts of their towns may not be exchanged for money, for it is their property for ever.
He is not to substitute it or exchange it the good with the bad or the bad with the good. If he ever makes an exchange of an animal for an animal, then it and what's being exchanged is holy.
He is not to examine it to see if it's good or bad or even exchange it. If he does exchange it, what has been exchanged as well as its substitute is sacred. It is not to be redeemed."
