Jesus confirmed the application of that prophecy to John, at Matthew 11:10, 11.
... 19-21. (a) Here, whom does Abraham picture, whom Isaac, and whom Jacob, and why? (b) So whom do the three together picture?
19 This was not saying that Abraham, Isaac and Jacob of old were then reclining at a table in the kingdom of the heavens; for these three men were not prophets greater than John the Baptist, and Jesus said, “A person that is a lesser one in the kingdom of the heavens is greater than him.” (Matt. 11:11, NW)
