Exodus 14:13-14

And Moses said unto the people, Fear ye not, stand still, and see the salvation of the LORD, which he will shew to you to day: for the Egyptians whom ye have seen to day, ye shall see them again no more for ever.

Moses said ... Fear ye not. Never, perhaps, was the fortitude of a man so severely tried as that of the Hebrew leader in this crisis, exposed as he was to various and inevitable dangers, the most formidable of which was the vengeance of a seditious and desperate multitude; but his meek, unruffled, magnanimous composure presents one of the sublimest examples of moral courage to be found in history. And whence did his courage arise? He saw the miraculous cloud still accompanying them, and his confidence arose solely from the hope of a divine interposition, although, perhaps, he might have looked for the expected deliverance in every quarter, rather than in the direction of the sea.
