Psalms 73:15

Psalms 73:15. If I say, I will speak thus; behold I should offend against the generation of thy children.

So he did not say what he thought. Some have said, "If you think so, you may as well say so." But not so. You might as well say if you have a match, you may as well burn your house down. Bad thought is bad to yourself, but it ends there; turn it into words and tell it to others and it may do an infinite mischief.
