Book of Ecclesiastes

When you vow a vow to God, don't defer to pay it; for he has no pleasure in fools. Pay that which you vow.

For as a dream comes with a multitude of cares, so a fool's speech with a multitude of words.

Don't be rash with your mouth, and don't let your heart be hasty to utter anything before God; for God is in heaven, and you on earth. Therefore let your words be few.

Guard your steps when you go to God's house; for to draw near to listen is better than to give the sacrifice of fools, for they don't know that they do evil.

There was no end of all the people, even of all them over whom he was--yet those who come after shall not rejoice in him. Surely this also is vanity and a chasing after wind.
