'Exchange' in the Bible
They shall not alter it nor change it, a good for a bad, or a bad for a good; and if he at all change beast for beast, then it and the exchange thereof shall be holy.
He shall not search whether it be good or bad, neither shall he change it; and if he change it at all, then both it and the exchange thereof shall be holy; it shall not be redeemed.
Now this was the custom in former time in Israel concerning redemption and concerning exchange, to confirm the whole matter: a man drew off his sandal, and gave it to his neighbour, and this was the mode of attestation in Israel.
Gold and glass cannot be compared to it, nor vessels of fine gold be its exchange.
And they shall not sell of it, neither exchange, nor alienate the first-fruits of the land: for it is holy unto Jehovah.
For what does a man profit, if he should gain the whole world and suffer the loss of his soul? or what shall a man give in exchange for his soul?
