Numbers 14:13-14

And Moses said unto Jehovah, Then the Egyptians will hear it; for thou broughtest up this people in thy might from among them; and they will tell it to the inhabitants of this land. They have heard that thou Jehovah art in the midst of this people; for thou Jehovah art seen face to face, and thy cloud standeth over them, and thou goest before them, in a pillar of cloud by day, and in a pillar of fire by night.
