Ecclesiastes 5:4-6

5:4 When you make a vow to God, do not delay in paying it.

For God takes no pleasure in fools:

Pay what you vow!

5:5 It is better for you not to vow

than to vow and not pay it.

5:6 Do not let your mouth cause you to sin,

and do not tell the priest, “It was a mistake!”

Why make God angry at you

so that he would destroy the work of your hands?”
