What does Luke 22:11 mean?
Jesus and the disciples have been in the Jerusalem area for about a week (John 12:1). Jesus has been spending His days teaching in the temple courtyard and His nights sleeping on the Mount of Olives (Luke 21:37). The disciples have witnessed Jesus' triumphal entry into Jerusalem, the cleansing of the temple, and many debates where Jesus destroyed the arguments of the religious leaders (Luke 19:28–46; 20). It's almost understandable if they've forgotten why they're there: to celebrate the Passover Feast.Jesus hasn't forgotten. He has been longing to have this moment with the disciples (Luke 22:15).
To prepare for the Passover Feast, the disciples must get a lamb, sacrifice it in the temple, and find bitter herbs, unleavened bread, fruit, and wine. On top of all that, they need a place to celebrate.
A proper site for the meal is the biggest obstacle. When Jesus tells Peter and John to prepare the meal, the location where they will eat dinner is their only question. Jesus gives them curious instructions: go into Jerusalem. By the gate, find a man carrying a jar of water. Follow him to a house (Luke 22:8–10).
The man should be easy enough to find; typically, it is the job of women to carry water. The man must be a servant if he is doing it. That means he doesn't own the house. So, it's reasonable for Peter and John to find and ask the homeowner if they can use a room.
Not only does the homeowner have a room, but it's already furnished (Luke 22:12). Peter and John do as Jesus says and go on to have one of the most important nights of their lives.
