Deuteronomy 14:25

Thou shalt then turn it into money
The tithe, which would be lighter and easier carriage:

and bind up the money in thine hand;
put it into a bag or purse, and tie it up and carry it in the hand; which some think was ordered, that it might not be mixed with other money; but it seems only to have respect to journeying, and making it fit for that. The Jewish writers {u}, some of them, give a different sense of the word we render "bind up", and interpret it of marking the silver, or impressing a form, figure, or image on it with the hand; they mean that it must be coined money; so Maimonides ^F23, they may not profane the sacred tithe with money not coined, nor with money not current, nor with money which is not in a man's power; for it is said,

in thine hand;
which the man is possessed of and is his own property:

and shalt go unto the place which the Lord that God shall choose;
carrying the money along with him, for which he sold the tithe.
