Luke 8:30 Meaning and Commentary

Luke 8:30

And Jesus asked him, saying, what is thy name?
&c.] This question was put, not out of ignorance in Christ, but for the sake of those that were with him; and partly, that the miserable condition of this man might be the more known; and partly, that his own power might be the more manifest in the dispossession:

and he said, legion, because many devils were entered into him;
(See Gill on Mark 5:9).

Luke 8:30 In-Context

28 When he saw Yeshua, he cried out, and fell down before him, and with a loud voice said, "What do I have to do with you, Yeshua, you Son of Ha`Elyon God? I beg you, don't torment me!"
29 For Yeshua was commanding the unclean spirit to come out of the man. For the unclean spirit had often seized the man. He was kept under guard, and bound with chains and fetters. Breaking the bands apart, he was driven by the demon into the desert.
30 Yeshua asked him, "What is your name?" He said, "Legion," for many demons had entered into him.
31 They begged him that he would not command them to go into the abyss.
32 Now there was there a herd of many pigs feeding on the mountain, and they begged him that he would allow them to enter into those. He allowed them.
