A lion found him, and slew him - This seems a hard measure, but there was ample reason for it. This person was also one of the sons of the prophets, and he knew that God frequently delivered his counsels in this way, and should have immediately obeyed; for the smiting could have had no evil in it when God commanded it, and it could be no outrage or injury to his fellow when he himself required him to do it.

Then said he unto him, because thou hast not obeyed the voice of the Lord,.... In not smiting him; which, if he was a prophet, he must know how great an evil it was to disregard or disobey what was said by a prophet in his name; he must be inexcusable:

behold, as soon as thou art departed from me, a lion shall slay thee.

And as soon as he was departed from him, a lion found him, and slew him; which may seem severe, yet being an act of disobedience to the command of God, by a prophet of his, was punishable with death.

Then said he unto him, Because thou hast not obeyed the voice of the LORD, behold, as soon as thou art departed from me, a lion shall {r} slay thee. And as soon as he was departed from him, a lion found him, and slew him.

(r) Because you have transgressed the commandment of the Lord.

20:36 Slew him - We cannot judge of the case; this man might be guilty of many other heinous sins unknown to us but known to God; for which, God might justly cut him off: which God chose to do upon this occasion, that by the severity of this punishment of a prophet's disobedience, proceeding from pity to his brother, he might teach Ahab the greatness of his sin, in sparing him through foolish pity, whom by the laws of religion, and justice, and prudence, he should have cut of.

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.
