LEB(i)
4 When you make a vow to God, do not delay in fulfilling it, for ⌊he takes no pleasure⌋* in fools. Fulfill what you vow!
5 It is better that you not vow than that you vow and not fulfill it.
6 Do not let your mouth lead your flesh into sin, and do not tell the messenger that it was a mistake. Why anger God at your words, so that he destroys the work of your hands?
