Ecclesiastes 5:3-5

5:3 Just as dreams come when there are many cares,

so the rash vow of a fool occurs when there are many words.

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.
