Ecclesiastes 5:2-4

Douay-Rheims 1899 American Edition

² Dreams follow many cares: and in many words shall be found folly.

³ If thou hast vowed any thing to God, defer not to pay it: for an unfaithful and foolish promise displeaseth him: but whatsoever thou hast vowed, pay it.

⁴ And it is much better not to vow, than after a vow not to perform the things promised.
