Matthew 21:8

And a very great multitude. — Better, the greater part of the multitude. Part of the crowd had come with Him from Galilee, part streamed from Bethany, excited by the recent resurrection of Lazarus (John 12:17). Some went before Him, some followed. As they advanced they were met by a fresh crowd pouring forth from Jerusalem. Of the latter, St. John records that they came out with palm-branches in their hands, as if to salute a king with the symbols of his triumph. (Comp. Revelation 7:9.)

Spread their garments in the way. — This, again, was a recognised act of homage to a king. So Jehu, when the officers of the army of Israel chose him as their ruler, walked upon the garments which they spread beneath his feet (2 Kings 9:13). So Agamemnon, tempted to an act of barbaric pomp, after the manner of Eastern kings, entered his palace at Mycenæ, walking upon costly carpets (Æschylus, Agam. 891).
