Adam Clarke on Luke 22:37

Must yet be accomplished - Probably meaning that, though this prophecy did refer to some particular matter in the time of the prophet, yet it farther (ετι) related to Christ, and could not have its complete accomplishment but in his crucifixion as a criminal.

For the things concerning me have an end - As if he had said, My work is now almost done; yours is only beginning; I am now about to be crucified and numbered with the transgressors; think what will be done to you, and what ought to be done by you; and then think if this be a time for you to be contending with each other. Lightfoot.
