Eclesiastes 5:6

6 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?

6 Let not your mouth make your flesh do evil. And say not before the angel, It was an error. So that God may not be angry with your words and put an end to the work of your hands.
