Ecclesiastes 5:1-2

Rash Vows

5:1 Be careful what you do when you go to the temple of God;

draw near to listen rather than to offer a sacrifice like fools,

for they do not realize that they are doing wrong.

5:2 Do not be rash with your mouth or hasty in your heart to bring up a matter before God,

for God is in heaven and you are on earth!

Therefore, let your words be few.

Ecclesiastes 1:18

1:18 For with great wisdom comes great frustration;

whoever increases his knowledge merely increases his heartache.
