7
Give to the good man, but do not help the sinner.
8
A friend will not be known in prosperity, nor will an enemy be hidden in adversity.
9
A man's enemies are grieved when he prospers, and in his adversity even his friend will separate from him.
10
Never trust your enemy, for like the rusting of copper, so is his wickedness.
11
Even if he humbles himself and goes about cringing, watch yourself, and be on your guard against him; and you will be to him like one who has polished a mirror, and you will know that it was not hopelessly tarnished.
