Do not say bad things and then say, “Oops, I did not mean it.” Do not tell the helper at God’s house, “It was a mistake.” Why make God mad? God can stop your work.
Do not let your mouth cause your flesh to sin, and do not tell the messenger that your vow was a mistake. Why should God be angry with your words and destroy the work of your hands?
KJV
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?
ASV
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?
