Numbers 20:6

And Moses and Aaron, dismissing the multitude, entered the tabernacle of the covenant, and they fell prone on the ground, and they cried out to the Lord, and they said: "O Lord God, listen to the outcry of this people, and open for them, from your storehouse, a fountain of living water, so that, being satisfied, their murmuring may cease." And the glory of the Lord appeared over them.
