2 And when He had come out of the boat, immediately there met Him out of the tombs a man with an unclean spirit, 3 who had his dwelling among the tombs; and no one could bind him, not even with chains, 4 because he had often been bound with shackles and chains. And the chains had been pulled apart by him, and the shackles broken in pieces; neither could anyone tame him. 5 And always, night and day, he was in the mountains and in the tombs, crying out and cutting himself with stones. 6 When he saw Jesus from afar, he ran and worshiped Him. 7 And he cried out with a loud voice and said, "What have I to do with You, Jesus, Son of the Most High God? I implore You by God that You do not torment me." 8 For He said to him, "Come out of the man, unclean spirit!" 9 Then He asked him, "What is your name?" And he answered, saying, "My name is Legion; for we are many." 10 Also he begged Him earnestly that He would not send them out of the country. 11 Now a large herd of swine was feeding there near the mountains. 12 So all the demons begged Him, saying, "Send us to the swine, that we may enter them." 13 And at once Jesus gave them permission. Then the unclean spirits went out and entered the swine (there were about two thousand); and the herd ran violently down the steep place into the sea, and drowned in the sea.

Commentary on Mark 5:1-20

(Read Mark 5:1-20)

Some openly wilful sinners are like this madman. The commands of the law are as chains and fetters, to restrain sinners from their wicked courses; but they break those bands in sunder; and it is an evidence of the power of the devil in them. A legion of soldiers consisted of six thousand men, or more. What multitudes of fallen spirits there must be, and all enemies to God and man, when here was a legion in one poor wretched creature! Many there are that rise up against us. We are not a match for our spiritual enemies, in our own strength; but in the Lord, and in the power of his might, we shall be able to stand against them, though there are legions of them. When the vilest transgressor is delivered by the power of Jesus from the bondage of Satan, he will gladly sit at the feet of his Deliverer, and hear his word, who delivers the wretched slaves of Satan, and numbers them among his saints and servants. When the people found that their swine were lost, they had a dislike to Christ. Long-suffering and mercy may be seen, even in the corrections by which men lose their property while their lives are saved, and warning given them to seek the salvation of their souls. The man joyfully proclaimed what great things Jesus had done for him. All men marvelled, but few followed him. Many who cannot but wonder at the works of Christ, yet do not, as they ought, wonder after him.
