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 of it, neither exchange, nor alienate the firstfruits of the land: for it is holy unto 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, whereof men bring an offering unto the Lord, all that any man giveth of such unto the Lord shall be holy.
A double-minded man is unstable in all his ways.
