For I say unto you, Ye shall not see me henceforth, till ye shall say, Blessed is he that cometh in the name of the Lord.
Christ departed as the sun sets, and with Him the light of life vanished from them. The word 'until' marks only the time before His going, not what follows after, just as Joseph knew not his wife until she bore Christ, yet afterward they lived as husband and wife. He means simply: I have taught you in humility and finished my work; I shall depart, and you cannot see me anymore in that office.
AI summary
Your day of mercy is finished. You rejected my offer of protection and salvation, and now judgment must fall on you as a nation until the time comes when you, long cast out and suffering, will hail me as the Messiah and say, Blessed is He that comes in the name of the Lord. That time has not yet come, but it will.

These are His last words to impenitent Jerusalem: the Shekinah, that visible glory which dwelt in the holy of holies, departs when He departs. The temple becomes deserted because its true Lord leaves it. Yet He promises that the day will come when the nation's Hosannas, once a stumbling block to the chief priests, shall break forth in glad acclaim to their pierced and acknowledged Messiah.
