Ecclesiastes 5:3-5

Wycliffe Bible

³ Dreams follow many busynesses, and folly shall be found in many words.

⁴ If thou hast avowed anything to God, tarry thou not to yield it; for an unfaithful and fond promise displeaseth him; but yield thou whatever thing thou hast avowed;

⁵ and it is much better to make not a vow, than after a vow to yield not the promises. (and it is much better to not make a vow, than to make a vow and then not yield the promises.)
