The deepest significance of this act of our Lord will be understood only when it is brought into direct connection with the history of His Passion. Voluntarily does the Lamb approach His murderers now that the time of slaughter has arrived. By such a public step He guards on the one hand against an assassination, and on the other hand brings on more rapidly His suffering and dying, for by this very act the hate of His enemies increases; Judas sees himself again deceived, when the Lord suffers even this opportunity of mounting an earthly throne to pass by unused; and while Jesus does nothing more to keep the enthusiasm of the multitude alive by brilliant miracles, the whole enthusiasm of the multitude at the end is nothing more than the last upstreaming brilliancy of an evening sun, before it vanishes beneath the horizon.
Lange’s Commentary on the Gospel of Luke, The Triumphal Entry
