When the meat offering was offered - i. e. about sunrise, when the morning sacrifice was offered. Compare 1 Kings 18:29.

There came water by the way of Edom - The Wady-el-Ahsy drains a considerable portion of northern Edom. Heavy rain had fallen during the night in some part of this tract, and with the morning a freshet of water came down the valley, filling the pits.

When the meat-offering was offered - This was the first of all offerings, and was generally made at sun-rising.

There came water - This supply was altogether miraculous, for there was neither wind nor rain, nor any other natural means by which it could be supplied.

And it came to pass in the morning, when the meat offering was offered,.... At Jerusalem; which always went along with the daily burnt offering of the lamb, which might not indeed be offered before break of day, yet quickly after; for no sacrifice could be offered before that; see Gill on Exodus 29:39,

that, behold, there came water by the way of Edom; not from the heavens, but it may be out of some rock, rolling along on the earth from the hills and mountains, down into the valleys, where the armies were:

and the country was filled with water; all round about them. Who has not heard of the "thundering" legion, as it was called by the Emperor M. Aurelius, who, when the army under him was about to engage with the Germans and Sarmatians, and sadly distressed with thirst, fell down on their knees and prayed, upon which a large shower of rain came down to the refreshment of the army, and thunder bolts, which annoyed and put the enemy to flight (i)? at the battle of the Romans with Jugurtha, a sudden and unexpected shower of rain fell, to the refreshment of the Romans, in intolerable thirst (k).

The water came in the morning at the time of the morning sacrifice (see 1 Kings 18:36), to indicate that the Lord was once more restoring His favour to the people on account of the sacrifice presented to Him in His temple.

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.

And it came to pass in the morning, when the meat offering was offered, that, behold, there came water by the way of Edom, and the country was filled with water.

3:20 The meal - offering - That is, the morning sacrifice: which doubtless was attended with the solemn prayers of God's people. At this time Elisha joined his prayers with the prayers of God's people, especially those at Jerusalem. And this time God chose to answer their prayers, and to work this miracle, that thereby he might determine the controversy between the Israelites and the Jews, about the place and manner of worship, and give a publick testimony from heaven for the Jews, and against the Israelites. God that commands all the waters both above and beneath the firmament, sent them abundance of water on a sudden.

20-24. when the meat offering was offered-that is, at the time of the morning sacrifice, accompanied, doubtless, with solemn prayers; and these led, it may be, by Elisha on this occasion, as on a similar one by Elijah (1Ki 18:36).

behold, there came water by the way of Edom-Far from the Israelitish camp, in the eastern mountains of Edom, a great fall of rain, a kind of cloudburst, took place, by which the wady was at once filled, but they saw neither the wind nor the rains. The divine interposition was shown by introducing the laws of nature to the determined end in the predetermined way [Keil]. It brought not only aid to the Israelitish army in their distress, by a plentiful supply of water, but destruction on the Moabites, who, perceiving the water, under the refulgent rays of the morning sun, red like blood, concluded the confederate kings had quarrelled and deluged the field with their mutual slaughter; so that, rushing to their camp in full expectation of great spoil, they were met by the Israelites, who, prepared for battle, fought and pursued them. Their country was laid waste in the way, which has always been considered the greatest desolation in the East (2Ki 3:24).

3:20-27 It is a blessing to be favoured with the company of those who have power with God, and can prevail by their prayers. A kingdom may be upheld and prosper, in consequence of the fervent prayers of those who are dear to God. May we place our highest regard upon such as are most precious in his account. When sinners are saying Peace, peace, destruction comes upon them: despair will follow their mad presumption. In Satan's service and at his suggestion, such horrid deeds have been done, as cause the natural feelings of the heart to shudder; like the king of Moab's sacrificing his son. It is well not to urge the worst of men to extremities; we should rather leave them to the judgment of God.
