Matthew 21:46
And although they were seeking to arrest him, they feared the crowds, because they held him to be a prophet. The fear of the crowds prevents the arrest that the chief priests and Pharisees want: the political calculation that governs their every move is still governing. The crowds who hold Jesus to be a prophet (verse 11) are the same crowds who prevent the religious establishment from acting against him in the open. The public constraints will require the private conspiracy of chapter 26.
