Jamieson, Fausset and Brown on Ezekiel 11:23

23. The Shekinah glory now moves from the east gate (Eze 10:4, 19) to the Mount of Olives, altogether abandoning the temple. The mount was chosen as being the height whence the missiles of the foe were about to descend on the city. So it was from it that Jesus ascended to heaven when about to send His judgments on the Jews; and from it He predicted its overthrow before His crucifixion (Mt 24:3). It is also to be the scene of His return in person to deliver His people (Zec 14:4), when He shall come by the same way as He went, "the way of the east" (Eze 43:2).
