Break forth into singing, O mountains

The whole multitude of the disciples began to rejoice and praise God with a loud voice for all the mighty works that they had seen; Saying, Blessed be the King that cometh in the name of the Lord: peace in heaven, and glory in the highest. 

And some of the Pharisees from among the multitude said unto him, Master, rebuke thy disciples. And [Jesus] answered and said unto them, I tell you that, if these should hold their peace, the stones would immediately cry out. (Luke 19: 37-40)
