...lest these stones cry out.
Along with the multitude which poured out to welcome the Master, there came also many of the Pharisees and his other enemies. They were so much perturbed by this sudden and unexpected outburst of popular acclaim that they feared to arrest him lest such action precipitate an open revolt of the populace. They greatly feared the attitude of the large numbers of visitors, who had heard much of Jesus, and who, many of them, believed in him.
As they neared Jerusalem, the crowd became more demonstrative, so much so that some of the Pharisees made their way up alongside Jesus and said: "Teacher, you should rebuke your disciples and exhort them to behave more seemly." Jesus answered: "It is only fitting that these children should welcome the Son of Peace, whom the chief priests have rejected. It would be useless to stop them lest in their stead these stones by the roadside cry out." ~ The Urantia Book, 172:3.12
