Do not be quick with your mouth, do not be hasty in your heart to utter anything before God.1 God is in heaven and you are on earth, so let your words be few.23
As a dream3 comes when there are many cares, so the speech of a fool when there are many words.44
When you make a vow to God, do not delay in fulfilling it.5 He has no pleasure in fools; fulfill your vow.65
It is better not to vow than to make a vow and not fulfill it.76
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?
