Nehemiah 9:10-12

10 and showed signs and wonders upon Pharaoh, and on all his servants, and on all the people of his land, for thou knew that they dealt proudly against them, and got thee a name, as it is this day.

11 And thou divided the sea before them, so that they went through the midst of the sea on the dry land. And thou cast their pursuers into the depths as a stone into the mighty waters.

12 Moreover in a pillar of cloud thou led them by day, and in a pillar of fire by night, to give them light in the way in which they should go.
