A spirit - "The spirit " - which some explain as "the evil spirit" - i. e. Satan; others as simply "the spirit" who should "persuade."

And there came forth a spirit,.... Not from the heavenly host on the right hand or the left, for they are pure and holy spirits, and impeccable, and cannot lie or deceive; but the evil spirit, Satan, the father of lies, the old deceiver, who came forth from his own place and his own company:

and stood before the Lord presented himself before him, as Satan did, Job 1:6,

and said, l will persuade him; or prevail upon him; evil spirits love to be employed in doing harm to men, they go about seeking whom they may devour. This could not be the spirit of Naboth, as the Jews say (q), seeking revenge on Ahab; that was in a state of happiness, could not move from thence, and be capable of sinning.

(q) T. Bab. Sanhedrin, fol. 89. 1. & 102. 2. Targum in 2 Chronicles 18.20.

And there came forth a spirit, and {q} stood before the LORD, and said, I will persuade him.

(q) Here we see that though the devil is always ready to bring us to destruction, yet he has no more power than God gives him.

22:21 A spirit - An evil spirit came, and presented himself before the throne.

22:15-28 The greatest kindness we can do to one that is going in a dangerous way, is, to tell him of his danger. To leave the hardened criminal without excuse, and to give a useful lesson to others, Micaiah related his vision. This matter is represented after the manner of men: we are not to imagine that God is ever put upon new counsels; or that he needs to consult with angels, or any creature, about the methods he should take; or that he is the author of sin, or the cause of any man's telling or believing a lie. Micaiah returned not the blow of Zedekiah, yet, since he boasted of the Spirit, as those commonly do that know least of the Holy Spirit's operations, the true prophet left him to be convinced of his error by the event. Those that will not have their mistakes set right in time, by the word of God, will be undeceived, when it is too late, by the judgments of God. We should be ashamed of what we call trials, were we to consider what the servants of God have endured. Yet it will be well, if freedom from trouble prove not more hurtful to us; we are more easily allured and bribed into unfaithfulness and conformity to the world, than driven to them.
