The help of God, which preserved the Israelitish army from destruction, also prepared destruction for the Moabites. 2 Kings 3:21-23. On hearing the report of the march of the allied kings, Moab had raised all the men that were capable of bearing arms, and stationed them on the frontier. In the morning, when the sun had risen above the water, the Moabites saw the water opposite to them like blood, and said: "That is blood: the (allied) kings have destroyed themselves and smitten one another; and now to the spoil, Moab!" Coming with this expectation to the Israelitish camp, they were received by the allies, who were ready for battle, and put to flight. The divine help consisted, therefore, not in a miracle which surpassed the laws of nature, but simply in the fact that the Lord God, as He had predicted through His prophet, caused the forces of nature ordained by Him to work in the predetermined manner. As the sudden supply of an abundance of water was caused in a natural way by a heavy fall of rain, so the illusion, which was so fatal to the Moabites, is also to be explained in the natural manner indicated in the text. From the reddish earth of the freshly dug trenches the water collected in them had acquired a reddish colour, which was considerably intensified by the rays of the rising sun, so that when seen from a distance it resembled blood. The Moabites, however, were the less likely to entertain the thought of an optical delusion, from the fact that with their accurate acquaintance with the country they knew very well that there was no water in the wady at that time, and they had neither seen nor heard anything of the rain which had fallen at a great distance off in the Edomitish mountains. The thought was therefore a natural one, that the water was blood, and that the cause of the blood could only have been that their enemies had massacred one another, more especially as the jealousy between Israel and Judah was not unknown to them, and they could have no doubt that Edom had only come with them as a forced ally after the unsuccessful attempt at rebellion which it had made a short time before; and, lastly, they cannot quite have forgotten their own last expedition against Judah in alliance with the Edomites and Ammonites, which had completely failed, because the men composing their own army had destroyed one another. But if they came into collision with the allied army of the Israelites under such a delusion as this, the battle could only end in defeat and in a general flight so far as they were concerned.
