Jesus saith unto them. Omitted by the Revised Version as a manifest gloss, perhaps originally due to a lectionary. Have ye understood. Our Lord wishes them to realize the progress that they have already made, that he may give them a fresh promise, and thus summon them to fresh energy.
All these things? Probably the immediately preceding parables and others spoken at the same time (cf. Matthew 13:34, note). They say unto him, Yea, Lord. Lord is rightly omitted by the Revised Version.
It distracts the attention from the quiet affirmative.
