Verse 34. - Let us alone; what have we to do with thee, thou Jesus of Nazareth? art thou come to destroy us? This man, with his evil spirit, would have been looked on as unclean, and would not have been admitted within the synagogue walls; he had probably crept in unseen. Something in the nearness to the holy Teacher we know compelled the demon to cry aloud. It is strange, this presence of God causing pain. It is the impossibility of the wounded eye bearing light. The cry rendered, "Let us alone," is scarcely the imperative of ἐάω, but an interjection, possibly the Greek reproduction of the Hebrew אֲהָהּ, ah! woe! There was evidently some deeper degree of misery possible for the unhappy spirit; hence its "Art thou come to destroy us?" The same dread appears in the case of the Gadarene demoniac (Mark 5:7; Matthew 8:29), where the spirits dreaded being driven into the deep, where such spirits await the judgment, that abyss, literally, "the bottomless place;" any doom seemed to these lost ones preferable to that. I know thee who thou art; the Holy One of God.
4:31-44 Christ's preaching much affected the people; and a working power went with it to the consciences of men. These miracles showed Christ to be a controller and conqueror of Satan, a healer of diseases. Where Christ gives a new life, in recovery from sickness, it should be a new life, spent more than ever in his service, to his glory. Our business should be to spread abroad Christ's fame in every place, to beseech him in behalf of those diseased in body or mind, and to use our influence in bringing sinners to him, that his hands may be laid upon them for their healing. He cast the devils out of many who were possessed. We were not sent into this world to live to ourselves only, but to glorify God, and to do good in our generation. The people sought him, and came unto him. A desert is no desert, if we are with Christ there. He will continue with us, by his word and Spirit, and extend the same blessings to other nations, till, throughout the earth, the servants and worshippers of Satan are brought to acknowledge him as the Christ, the Son of God, and to find redemption through his blood, even the forgiveness of sins.
Saying, let us alone,.... Not that there were more spirits in him than one, as the whole account shows; but he includes the rest of the devils in that country; See Gill on Mark 1:24.
