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 both it and that for which it is changed shall be holy.
If any one commit a trespass, and sin unwittingly, in the holy things of Jehovah; then he shall bring his trespass-offering unto Jehovah, a ram without blemish out of the flock, according to thy estimation in silver by shekels, after the shekel of the sanctuary, for a trespass-offering:
Suffer not thy mouth to cause thy flesh to sin; neither say thou before the angel, that it was an error: wherefore should God be angry at thy voice, and destroy the work of thy hands?
