Exodus 17:6

Before thee, ready to grant thy request at Horeb, a rock to the west of Sinai, and a figure of Jesus Christ, according to St. Paul; who says, (1 Corinthians x. 4,) that the spiritual rock followed the Hebrews. Some say a part of the real rock was carried in a chariot. (St. Chrysostom) Others, that the rivulet of waters accompanied them till it fell into the sea near Asiengaber. (Usher.) --- The Rabbins say, that these waters never failed the Israelites till the death of Mary, for whose sake they were given, and that the bright cloud disappeared with Aaron, and manna at the decease of Moses.
