Ecclesiastes 5:4-6

Douay-Rheims 1899 American Edition

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

⁵ Give not thy mouth to cause thy flesh to sin: and say not before the angel: There is no providence: lest God be angry at thy words, and destroy all the works of thy hands.

⁶ Where there are many dreams, there are many vanities, and words without number: but do thou fear God.
