Answer:
The phrase bind the strong man (or strongman) is a reference to a passage in the book of Mark, where Jesus is responding to some Jewish scribes who were accusing Him of being possessed by Beelzebul. Their argument was that “by the prince of demons he is driving out demons” (Mark 3:22). In other words, the reason the demons listened to Jesus was that they were in league with Him and recognized Him as their commanding officer, so to speak.
