首楞嚴義疏注經 7.116

7.116

說是語已，會中無量百千金剛，一時佛前合掌頂禮而白佛言：「如佛所說，我當誠心保護如是修菩提者。」

When these words were spoken, immeasurable hundreds of thousands of vajra beings in the assembly joined their palms simultaneously, bowed with their heads at the Buddha's feet, and addressed the Buddha, saying: "As the Buddha has spoken, we shall sincerely protect such practitioners of bodhi."
