But if he is too poor to pay your valuation, then he shall present himself before the priest, and the priest shall value him; according to his ability that vowed shall the priest value him.
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.
If a soul commits a trespass, and sins through ignorance, in the holy things of the LORD; then he shall bring for his trespass unto the LORD a ram without blemish out of the flocks, with your valuation by shekels of silver, after the shekel of the sanctuary, for a trespass offering:
Permit not your mouth to cause your flesh to sin; neither say before the angel, that it was an error: why should God be angry at your voice, and destroy the work of your hands?
