A harsh message of rebuke highlights the tragic gap between divine kindness and human failure. God reminds the king of his humble beginnings, noting that before his rise to power, he was merely an ordinary man. God actively lifted him up, separating him from his lowly status [מצודת ציון] to appoint him as the ruler over the nation.
Yet, despite receiving such immense goodness, the king chose to turn his back. Instead of showing gratitude for his elevation, he followed a destructive path. He not only sinned himself but actively caused the entire nation of Israel to sin, acting in a way that deliberately angered God [ביאור שטיינזלץ].
