Do not allow your mouth to cause your flesh to sin; do not say before the angel that it was an error. Why should God be angry at your voice and destroy the work of your hands?
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 of it shall be holy.
But if he is poorer than your judgment, then he shall present himself before the priest, and the priest shall value him. The priest shall value him according to the ability of him who vowed.
If a soul commits a trespass and sins through ignorance in the holy things of Jehovah, then he shall bring for his trespass to Jehovah a ram without blemish out of the flock, together with an amount set by you, by shekels of silver, after the shekel of the sanctuary, for a trespass offering.
