Luke 22:10-12

It was unusual for men to carry pitchers of water. Usually women did and men carried water in leather skins. [Note: Marshall, The Gospel . . ., p. 791; Liefeld, "Luke," p. 1025.] This appears to have been a prearranged signal that was part of Jesus’ plan to avoid an early arrest. Judas would not have known where the upper room was since Jesus informed Peter and John of its location as He did. The title "teacher" (Gr. didaskalos) was one that Jesus’ disciples used to describe Him (cf. Luke 6:40). Evidently the owner of the upper room was a disciple. The upper room probably stood on the flat roof of a typical Palestinian house and served as an extra room. It would have been accessible by an external stairway. The owner would have furnished it with cushions for reclining on at least. [Note: Jeremias, The Eucharistic . . ., p. 48, footnote 1.] Traditionally the upper room was on Mt. Zion just to the north and east of the Hinnom Valley and west of the City of David. [Note: See the diagram "Jerusalem in New Testament Times" at the end of these notes.]
