35 Now a certain man of the sons of the prophets said to his neighbor by the word of the Lord, "Strike me, please." And the man refused to strike him. 36 Then he said to him, "Because you have not obeyed the voice of the Lord, surely, as soon as you depart from me, a lion shall kill you." And as soon as he left him, a lion found him and killed him. 37 And he found another man, and said, "Strike me, please." So the man struck him, inflicting a wound. 38 Then the prophet departed and waited for the king by the road, and disguised himself with a bandage over his eyes. 39 Now as the king passed by, he cried out to the king and said, "Your servant went out into the midst of the battle; and there, a man came over and brought a man to me, and said, 'Guard this man; if by any means he is missing, your life shall be for his life, or else you shall pay a talent of silver.' 40 While your servant was busy here and there, he was gone." Then the king of Israel said to him, "So shall your judgment be; you yourself have decided it." 41 And he hastened to take the bandage away from his eyes; and the king of Israel recognized him as one of the prophets. 42 Then he said to him, "Thus says the Lord: 'Because you have let slip out of your hand a man whom I appointed to utter destruction, therefore your life shall go for his life, and your people for his people.' "

Commentary on 1 Kings 20:31-43

(Read 1 Kings 20:31-43)

This encouragement sinners have to repent and humble themselves before God; Have we not heard, that the God of Israel is a merciful God? Have we not found him so? That is gospel repentance, which flows from an apprehension of the mercy of God, in Christ; there is forgiveness with him. What a change is here! The most haughty in prosperity often are most abject in adversity; an evil spirit will thus affect a man in both these conditions. There are those on whom, like Ahab, success is ill bestowed; they know not how to serve either God or their generation, or even their own true interests with their prosperity: Let favour be showed to the wicked, yet will he not learn righteousness. The prophet designed to reprove Ahab by a parable. If a good prophet were punished for sparing his friend and God's when God said, Smite, of much sorer punishment should a wicked king be thought worthy, who spared his enemy and God's, when God said, Smite. Ahab went to his house, heavy and displeased, not truly penitent, or seeking to undo what he had done amiss; every way out of humour, notwithstanding his victory. Alas! many that hear the glad tidings of Christ, are busy and there till the day of salvation is gone.
