Let not your mouth lead you into sin, and do not say before the messenger that it was a mistake; why should God be angry at your voice, and destroy the work of your hands?
Be not rash with your mouth, nor let your heart be hasty to utter a word before God, for God is in heaven, and you upon earth; therefore let your words be few.
