Is that what God says? ... Unbreakable chains

1 So they came to the other side of the lake, to the region of the Gerasenes. 2 Just as Jesus was getting out of the boat, a man with an unclean spirit came from the tombs and met him. 3 He lived among the tombs, and no one could bind him anymore, not even with a chain. 4 For his hands and feet had often been bound with chains and shackles, but he had torn the chains apart and broken the shackles in pieces. No one was strong enough to subdue him. 5 Each night and every day among the tombs and in the mountains, he would cry out and cut himself with stones. 6 When he saw Jesus from a distance, he ran and bowed down before him. 7 Then he cried out with a loud voice, "Leave me alone, Jesus, Son of the Most High God! I implore you by God - do not torment me!" 8 (For Jesus had said to him, "Come out of that man, you unclean spirit!") 9 Jesus asked him, "What is your name?" And he said, "My name is Legion, for we are many." 10 He begged Jesus repeatedly not to send them out of the region. 11 There on the hillside, a great herd of pigs was feeding. 12 And the demonic spirits begged him, "Send us into the pigs. Let us enter them." (Mark 5)

I was thinking about when people bind a demon in or with unbreakable chains, and wondering where that comes from!

My theory (which was blown out of the water) was maybe it has something to do with the above passage of scripture! I don't know.

So if someone does know the relevant scripture verses that support the unbreakable chains idea, please share!

May Gods blessings shower down upon you. And may you be coated in the dust of your Rabbi!
