Origen
Catena Aurea · Lukasevangelium 19
And when he was come nigh, even now at the descent of the mount of Olives, 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 he answered and said unto them, I tell you that, if these should hold their peace, the stones would immediately cry out
When we also are silent, (that is, when the love of many waxeth cold,) the stones cry out, for God can from stones raise up children to Abraham.
