Luke 20:26 earlier in the same chapter describes the opponents becoming silent — directly parallel to their later inability to ask.

Luke 13:17 similarly reports that all his adversaries were put to shame — echoing the theme of opponents silenced.

Luke 14:6 records that opponents could not reply to Jesus' Sabbath question — another instance of silencing.

Matthew 22:46 records the same reaction — no one dared to ask him any more questions after Jesus silenced the Sadducees.

Mark 12:34 also notes that no one dared to ask him any more questions, preserving the identical outcome.
