Then there came out a spirit - The Targum gives a strange gloss here: "Then the spirit of Naboth of Jezreel came out from the abode of the righteous, and stood before the Lord, and said, I will deceive him. And the Lord said, By what means? To which he answered, I will be a spirit of false prophecy in the mouth of his prophets. And the Lord said, Thou mayest then. But although the power of deceiving them is given unto thee, nevertheless it will not be lawful for thee to sit among the righteous; for whosoever shall speak falsely cannot have a mansion among the righteous. Therefore go forth from me, and do as thou hast said." - Targum.

Then there came out a spirit, and stood before the LORD, and said, I will entice him. And the LORD said unto him, Wherewith?

18:1-34 Jehoshaphat's alliance with Ahab. - This history we read in 1Ki 22. Abundant riches and honour give large opportunities of doing good, but they are attended with many snares and temptations. Men do not know much of the artifices of Satan and the deceitfulness of their own hearts, when they covet riches with the idea of being able to do good with them. What can hurt those whom God will protect? What can shelter those whom God will destroy? Jehoshaphat is safe in his robes, Ahab killed in his armour; for the race is not to the swift, nor the battle to the strong. We should be cautious of entangling ourselves in the worldly undertakings of evil men; and still more we should avoid engaging in their sinful projects. But, when they call upon him, God can and will bring his faithful people out of the difficulties and dangers into which they have sinfully run themselves. He has all hearts in his hand, so that he easily rescues them. Blessed is the man that putteth his trust in the Lord.
