2 Samuel 23:3
The God of Israel said, the Rock of Israel spake to me, He that ruleth over men must be just, ruling in the fear of God. The God of Israel said, the Rock of Israel spake to me, He that ruleth over men must be just, ruling in the fear of God.
Anyone who rules over people is commanded to be just, ruling in reverence for God. Those in leadership are to reflect God's light through their conduct. The words are God's own speech to David, spoken through him by the Spirit of the Lord. Such just rule is bright, life-giving and hopeful, like clear morning light and fresh grass growing after rain. The song sets David's imperfect house over against God's sure, everlasting covenant, which is his salvation and his desire. David applied this standard to Solomon's kingship, so that by faithful rule with mercy and loving-kindness to subjects and honor toward God in dealings with other nations his reign would be righteous.
David's instruction was meant to guide himself and all who would rule after him. Rulers are accountable to God and govern under His authority. They must not rely on human judgment to watch over and dictate to others but must look to God for counsel, for ruling by human judgment brings confusion and dishonors God. Those entrusted with rule should stay humble, recognizing that they are not God, depend on His wisdom rather than their own strength, and express His will without selfishness or compromise. Those who rule should be self-controlled, live peaceably in obedience to God's commandments, and reflect God's light through their conduct. Christ's example shows that justice, mercy, and love are the principles that govern God's kingdom. A ruler's conduct can either guide people toward God or lead them astray.
