Proverbs 24:8

In context

6For with guidance you wage your war, and victory lies in many counselors. 7Wisdom is too high for the senseless; at the gate he does not open his mouth. 8Whoever plots to do harm—men will call him a schemer. 9The scheming of folly is sin, and the scoffer is an abomination to men. 10If you go slack on the day of trouble, your strength is small indeed.
