Psalm 78:12-16

12In the sight of their fathers he performed wonders
   in the land of Egypt, in the fields of Zoan. 13He divided the sea and let them pass through it,
   and made the waters stand like a heap. 14In the daytime he led them with a cloud,
   and all the night with a fiery light. 15He split rocks in the wilderness
   and gave them drink abundantly as from the deep. 16He made streams come out of the rock
   and caused waters to flow down like rivers.
