Do not let your mouth lead you into sin. And do not protest to the temple messenger, "My vow was a mistake." Why should God be angry at what you say and destroy the work of your hands?
Do not allow your mouth to cause your body to sin, and do not say before the messenger [the priest] that it was an error or mistake. Why should God be [made] angry at your voice and destroy the work of your hands? [Mal. 2:7.]AMP
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 thine hands?
