Ecclesiastes 10:2

A wise man's heart is at his right hand, but a fool's heart at his left.

The wisdom of a prudent man is to understand his way, but the folly of fools is deceit.

Why is there a price in the hand of a fool to buy wisdom, since he has no understanding?

Whatever thy hand finds to do, do with thy might, for there is no work, nor device, nor knowledge, nor wisdom, in Sheol, where thou go.

If the iron be blunt, and he does not whet the edge, then he must increase strength. But wisdom is advantageous to make right.

A fool also multiplies words; [yet] man knows not what shall be, and that which shall be after him, who can tell him?

And he said, I will do this. I will dismantle my barns, and I will build greater, and there I will store all my grain and my goods.

For which of you wanting to build a tower, does not, having first sat down, count the cost whether he has the things for completion?
