Mark 9:14

“And when he came to his disciples, etc..] The other nine, who were left at the bottom of the mountain, and were waiting for him: he saw a great multitude about them: there was a multitude that followed him from Bethsaida hither; and which, very likely, was greatly increased upon Christ's arrival in those parts, and the people hearing of it; and the Scribes questioning with them; disputing and contending with them about their master, his doctrines and miracles, and their mission and authority from him; insulting them, on account of their inability to dispossess a dumb spirit, hereafter related.”

This account is similar to the story of Moses descending from Mount Sinai to rejoin the people of Israel (Exod 34:29-35).”
