Proverbs 24:9

Thought. Heb. zimmah, “plan,” “device,” “wickedness.” Only here is zimmah translated “thought.” Elsewhere it is rendered “wickedness” (Lev. 18:17; etc.), “mischief” (Ps. 26:10; etc.), “wicked devices” (Isa. 32:7), “lewdness” (Jer. 13:27; etc.). Evidently it is not the thinking about foolishness that is here pointed out as sin, but rather the planning of the sort of folly mentioned in Prov. 24:8.

Scorner. Men may hesitate to describe as a fool the shrewd and subtle scoffer, who can undermine a truth while pretending to defend it, but they hate and fear him because his attacks are so insidious (see Prov. 19:29; 21:11; Isa. 29:20).
