"He clave the rocks in the wilderness, and gave them drink as out of the great depths. He brought streams also out of the rock, and caused waters to run down like rivers." Psalm 78:15, 16. Moses smote the rock, but it was the Son of God who, veiled in the cloudy pillar, stood beside Moses, and caused the life-giving water to flow. Not only Moses and the elders, but all the congregation who stood at a distance, beheld the glory of the Lord; but had the cloud been removed, they would have been slain by the terrible brightness of Him who abode therein.

Han kløvede klipper i ørkenen, lod dem rigeligt drikke som af strømme, han lod bække rinde af klippen og vand strømme ned som floder. Sl. 78, 15-16. Moses slog på klippen, men det var Guds Søn, der skjult i skystøtten stod ved siden af ham og fik det livgivende vand til at flyde. Både Moses, de ældste og hele menigheden, der stod i nogen afstand, så Guds herlighed; men hvis skyen var blevet fjernet, ville de være blevet fortæret af den frygtelige stråleglans fra ham, som opholdt sig i den.
