A.T. Robertson Commentary Matthew 23:29

"Woe unto you, scribes and Pharisees, hypocrites! for ye build the sepulchres of the prophets, and garnish the tombs of the righteous," — Matthew 23:29 (ASV)

The tombs of the prophets (τους ταφους των προφητων). Cf. Luke 11:48–52. They were bearing witness against themselves (εαυτοις, verse 31) to "the murder-taint in your blood" (Allen). "These men who professed to be so distressed at the murdering of the Prophets, were themselves compassing the death of Him who was far greater than any Prophet" (Plummer). There are four monuments called Tombs of the Prophets (Zechariah, Absalom, Jehoshaphat, St. James) at the base of the Mount of Olives. Some of these may have been going up at the very time that Jesus spoke. In this seventh and last woe Jesus addresses the Jewish nation and not merely the Pharisees.
