He shall not alter it, nor change it, a good for a bad, or a bad for a good: and if he shall at all change beast for beast, then it and the exchange thereof shall be holy.
And they shall not sell any of it, neither exchange, nor misuse the first fruits of the land: for it is holy to the LORD.
And if it be any unclean beast, of which they do not offer a sacrifice unto the LORD, then he shall present the beast before the priest:
And if it be a beast, of which men bring an offering to the LORD, all that any man gives of such unto the LORD shall be holy.
A double minded man is unstable in all his ways.
