Numbers 14:13-14

And Moses said unto the LORD, Then the Egyptians shall 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: {for} they have heard that thou LORD {art} among this people, that thou LORD art seen face to face, and {that} thy cloud standeth over them, and {that} thou goest before them, by day time in a pillar of a cloud, and in a pillar of fire by night.
