Proverbs 17:16-18

Amplified Bible

¹⁶ 
Why is there money in the hand of a fool to buy wisdom,
When he has no common sense or even a heart for it?
¹⁷ 
A friend loves at all times,
And a brother is born for adversity.
¹⁸ 
A man lacking common sense gives a pledge
And becomes guarantor [for the debt of another] in the presence of his neighbor.
