Proverbs 21:4 An high look, and a proud heart, and the plowing of the wicked, is sin.
This proverb identifies three ordinary expressions of wickedness, not dramatic crimes, but everyday sins that humans excuse, polish, and parade as normal behaviour.
‘A high (haughty) look.’ This refers to an outward expression of inward pride. The eyes reveal contempt, self-importance, and superiority over others. God repeatedly condemns this attitude because it places the self above both God and man (Prov. 6:17; Ps. 101:5). Pride rarely begins with actions; it begins with a look that silently says, “I am above you.”
‘A proud heart.’ The inner source of the high look. Pride is not merely arrogance but rebellion against dependence on God. A proud heart trusts itself, justifies itself, and resists correction. Scripture consistently pairs pride with divine opposition (Ps. 101:5; Prov. 16:5). God does not negotiate with pride; He opposes it.
‘The plowing (tilling, works) of the wicked.’ This is the most unsettling part of the verse. Even productive, diligent labour becomes sin when it proceeds from a wicked heart. “Plowing” represents ordinary activity, planning, effort, and enterprise. The proverb teaches that wickedness contaminates even neutral or commendable actions. Work done without regard for God, righteousness, or obedience is not morally neutral; it is sinful because its purpose is self-serving rather than God-honouring (cf. Prov. 15:8).
Together, these three show that sin is not limited to immoral acts. Attitude, motivation, and direction matter. Pride poisons perception, intention, and effort alike.
