Charles Ellicott Commentary Luke 22:39

"And he came out, and went, as his custom was, unto the mount of Olives; and the disciples also followed him." — Luke 22:39 (ASV)

And went, as he was wont, to the mount of Olives.—The words agree with the previous statement in Luke 21:37, and with John 18:2. Here, as in the parallel passage of Matthew 26:30 (where see Note), we have to insert the discourses of John 14-17.
