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 animal for animal, then it and the exchange thereof shall be holy.
And they shall not sell any of it, neither exchange, nor alienate the firstfruits of the land: for it is holy unto the LORD.
And if it be any unclean animal, of which they do not offer a sacrifice unto the LORD, then he shall present the animal before the priest:
And if it be an animal, of which men bring an offering unto 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.
