2 Kings 3:20
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.
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}.
