Ecclesiastes 5:2-6

2Do not be rash with your mouth, And let not your heart utter anything hastily before God. For God is in heaven, and you on earth; Therefore let your words be few.

3For a dream comes through much activity, And a fool’s voice is known by his many words.

4When you make a vow to God, do not delay to pay it; For He has no pleasure in fools. Pay what you have vowed—

5Better not to vow than to vow and not pay.

6Do not let your mouth cause your flesh to sin, nor say before the messenger of God that it was an error. Why should God be angry at your excuse and destroy the work of your hands?
