¹⁸ 
A man lacking common sense gives a pledge
And becomes guarantor [for the debt of another] in the presence of his neighbor.
¹⁹ 
He who loves transgression loves strife and is quarrelsome;
He who [proudly] raises his gate seeks destruction [because of his arrogant pride].
²⁰ 
He who has a crooked mind finds no good,
And he who is perverted in his language falls into evil.^(A)
