'Looked' in the Bible

Now it happened that while Joshua was near Jericho, he looked up and much to his amazement, he saw a man standing in front of him, holding a drawn sword in his hand! Joshua approached him and asked him, "Are you one of us, or are you with our enemies?"

Then the men of Ai looked back behind them and all of a sudden! smoke from the city was rising into the sky. They were unable to run in any direction, because the Israelis who had fled toward the wilderness had turned around to attack their pursuers.
