Ecclesiastes 5:4-7

⁴If 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;

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

⁶Give thou not thy mouth, that thou make thy flesh to do sin; neither say thou before an angel, No purvey-ance there is; lest peradventure the Lord be wroth on thy words, and destroy all the works of thine hands.

⁷Where be many dreams, be full many vanities, and words without number; but dread thou God.
