17A friend loves at all times, and a brother is born for adversity.
18A man lacking judgment strikes hands in pledge and puts up security for his neighbor.
19He who loves transgression loves strife; he who builds his gate high invites destruction.
20The one with a perverse heart finds no good, and he whose tongue is deceitful falls into trouble.
21A man fathers a fool to his own grief; the father of a fool has no joy.
