“And when the disciples heard it, they fell on their face, and were sore afraid.”
King James Version (KJV)
17:4 Let us make three tents - The words of rapturous surprise. He says three, not six: because the apostles desired to be with their Master.
17:5 Hear ye him - As superior even to Moses and the prophets. See #Deut 18:17|.
17:7 Be not afraid - And doubtless the same moment he gave them courage and strength.
Mt 17:6 They . . . were sore afraid. Like the children of Israel at Sinai, they were filled with awe at the Divine voice (Ex 19:9,16).
