Mark 5:9 records Jesus asking a tormented man to name himself, and the answer, “Legion,” reveals that the man was held by many unclean spirits, not one. The verse shows Jesus drawing out the truth of a suffering person’s condition before setting him free. Mark, the Gospel writer, reports the exchange as Jesus speaks to the demon or demons inhabiting the man, and the demon answers on their behalf.
He asked him, “What is your name?” He said to him, “My name is Legion, for we are many.”

What Mark 5:9 Means
Jesus begins with a question, “What is your name?” In the ancient world a name was tied to identity and authority, so asking it was a way of confronting what held the man. The spirit does not give a simple name like a person would. Instead it answers “Legion,” a term for a Roman military unit that could number several thousand soldiers. The word signals overwhelming numbers and organized force.
The second half, “for we are many,” explains the name. The man was not occupied by one spirit but by a crowd of them. The verse does not promise that Jesus will always ask our names in a visible way, nor does it tell us how the spirits came to the man. What it does show is that Jesus knows exactly what he is dealing with, however large or hidden the oppression.
The Context of Mark 5:9
Mark’s Gospel is short, fast-moving, and written to show Jesus as the powerful Son of God who acts with authority. It was likely written for a Roman or Gentile audience, which helps explain why a Roman military term appears here. The story of the Gerasene demoniac takes place in Gentile territory across the Sea of Galilee, so the setting itself points to Jesus’s reach beyond the Jewish community.
Just before verse 9, the demon recognizes Jesus and begs him not to torment it. Right after, the spirits ask to be sent into a herd of pigs, which Jesus allows. Read in this sequence, the question about the name is the hinge of the scene: the spirits are exposed, their number is revealed, and then Jesus’s power over them is displayed.

A Short Prayer From Mark 5:9
Lord Jesus, you asked the man who he was and heard the truth of his torment. I bring you the parts of my life that feel crowded and overwhelming, the fears and habits that seem to speak with many voices at once. Help me name them honestly before you, and give me the courage to let you bring light to each one. Thank you that nothing is too large or too hidden for your authority. Restore what has been broken and keep me close to you. Amen.
