Now viewing scripture range from the book of Ecclesiasticus chapter 12:7 through chapter 12:10...
7 Give unto the good, and help not the sinner.
8 A friend cannot be known in prosperity: and an enemy cannot be hidden in adversity.
9 In the prosperity of a man enemies will be grieved: but in his adversity even a friend will depart.
10 Never trust thine enemy: for like as iron rusteth, so is his wickedness.
