Mark 5:1-20 (NASB)
They came to the other side of the sea, into the country of the Gerasenes. When He got out of the boat, immediately a man from the tombs with an unclean spirit met Him, and he had his dwelling among the tombs. And no one was able to bind him anymore, even with a chain; because he had often been bound with shackles and chains, and the chains had been torn apart by him and the shackles broken in pieces, and no one was strong enough to subdue him. Constantly, night and day, he was screaming among the tombs and in the mountains, and gashing himself with stones. Seeing Jesus from a distance, he ran up and bowed down before Him; and shouting with a loud voice, he said, "What business do we have with each other, Jesus, Son of the Most High God? I implore You by God, do not torment me!" For He had been saying to him, "Come out of the man, you unclean spirit!" And He was asking Him, "What is your name?" And he said to Him, "My name is Legion; for we are many." And he began to implore Him earnestly not to send them out of the country. Now there was a large herd of swine feeding nearby on the mountain. The demons implored Him, saying, "Send us into the swine so that we may enter them." Jesus gave them permission. And coming out, the unclean spirits entered the swine; and the heard rushed down the steep bank into the sea, about two thousand of them; and they were drowned in the sea. Their herdsmen ran away and reported it in the city and in the country. And the people came to see what it was that had happened. They came to Jesus and observed the man who had been demon-possessed sitting down, clothed and in his right mind, the very man who had the "legion"; and they became frightened. Those who had seen it described to them how it had happened to the demon-possessed man, and all about the swine. And they began to implore Him to leave their region. As He was getting into the boat, the man who had been demon-possessed was imploring Him that he might accompany Him. And He did not let him, but He said to him, "Go home to your people and report to them what great things the Lord has done for you, and how He had mercy on you." And he went away and began to proclaim in Decapolis what great things Jesus had done for him; and everyone was amazed.
Romans 11:7-15 (KJV)
What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were blinded. (According as it is written, God hath given them the spirit of slumber, eyes that they should not see, and ears that they should not hear;) unto this day. And David saith, Let their table be made a snare, and a trap, and a stumblingblock, and a recompence unto them: Let their eyes be darkened, that they may not see, and bow down their back alway. I say then, Have they stumbled that they should fall? God forbid: but rather through their fall salvation is come unto the Gentiles, for to provoke them to jealousy. Now if the fall of them be the riches of the world, and the diminishing of them the riches of the Gentiles; how much more their fulness? For I speak to you Gentiles, inasmuch as I am the apostle of the Gentiles, I magnify mine office: If by any means I may provoke to emulation them which are my flesh, and might save some of them. For if the casting away of them be the reconciling of the world, what shall the receiving of them be, but life from the dead?
