17A true friend is always there to love you, and family provides help when troubles come.
18It's not a wise idea to make a pledge and guarantee a neighbor's debt.
19People who love sin like to argue; those who build high gates invite destruction.
20People with warped minds don't succeed; those who tell lies get into trouble.
21A stupid son brings grief to his father; the father of a child who does stupid things has no joy.
