Matthew 22:46

‘And no one was able to answer him a word, neither dared any man from that day forth to ask him any more questions.'

Once again they could give Him no answer, for they had to mentally acknowledge the truth of what He said. But they were not willing to receive it into their hearts, and there is a sense in which at this moment they finally sealed their fate, as described in what follows in 23 onwards, because of the hardening of their hearts.

It was also the end of trying to test Jesus out. No one from that day on dared to ask Him any more questions. So they withdrew to lick their wounds, and began instead to plot His death. They now recognised that it was the only way in which they could defeat Him. It was the recognition of their intellectual and spiritual dishonesty in this that caused Jesus to speak as He does in chapter 23. They had as a body proved themselves to be beyond redemption.
