2 Kings 1:9
Then the king sent unto him a captain of fifty with his fifty. And he went up to him: and, behold, he sat on the top of an hill. And he spake unto him, Thou man of God, the king hath said, Come down. Then the king sent unto him a captain of fifty with his fifty. And he went up to him: and, behold, he sat on the top of an hill. And he spake unto him, Thou man of God, the king hath said, Come down.
This verse belongs to the history of the fall of the house of Ahab. It stands in the closing part of that history, when the evil influence that Jezebel had exercised over Ahab from the first continued through the later years of his life and bore fruit in deeds of shame and violence seldom equaled in sacred history. More specifically, it belongs to the history of Ahaziah's sin and punishment, the account of Elijah's protest when Ahaziah turned from the living God to Baal-zebub, the god of Ekron.
The verse shows Ahaziah sending a captain with fifty soldiers to Elijah as he sat on the top of a hill, commanding him in the king's name to come down, in an attempt to intimidate him. The first two companies sent on this errand were destroyed by God's judgment, while the third captain humbled himself and pleaded for his own life and the lives of his men, after which Elijah went with him to the king. James and John later appealed to the destruction of the captains and their companies in this passage when they asked to call down fire on the Samaritans, but Jesus rebuked them, for his mission was to save lives, not to destroy them.
That rebuke teaches that zeal for Christ must be shaped by his spirit of meekness, humility, and love. Ahaziah's course warns against turning from God to heathen worship and seeking knowledge apart from him. Idolatry can take refined forms and still serve Satan, and declining faith in prophecy gives way to superstition and deception. Those who do not search Scripture, test their desires and purposes by it, and pray for knowledge of God's will risk leaving the right path and being deceived.
