In Jeremiah 46:3-6 we saw only a mighty army marshalling for battle, and its hasty flight. In Jeremiah 46:7-12 the prophet tells us at whose defeat we have been present.

A flood - the Nile. The metaphor describing the advance of the Egyptian army is naturally drawn from the annual overflow of their own sacred stream.

Whose waters are moved ... - literally, his waters toss to and fro as the rivers, the natural branches of the Nile in Lower Egypt.

Who is this that cometh up as a flood - The vast concourse of people is here represented as a river: for instance, the Jordan, suddenly swollen with the rains in harvest, rolling its waters along, and overflowing the whole country. A fine image to represent the incursions of vast armies carrying all before them. Such was the army of Pharaoh-necho in its march to Carchemish.

Who is this that cometh up as a flood,.... These are either the words of the prophet, who having a vision in prophecy of the march of the Egyptian army from the south to the north, which he compares to a flood; in allusion to the river Nile, which used to overflow its banks, and spread itself over the land; because of the vast numbers of which it consisted; because of the noise it made, and, because of its rapidity and force, threatening to bear all down before it; as wondering, asks, who it was, whose army it was, and to whom it belonged? or they are the words of God, who puts this question, in order to, give an answer to it, and thereby upbraid the Egyptians with their arrogance, pride, and vanity; which would all come to nothing:

whose waters are moved as the rivers? whose numerous armies came with a great noise and force, like the openings of the Nile, the seven gates of it; which were very boisterous, especially in hard gales of wind: it is no unusual thing for large armies to be compared to floods and rivers, which move forcibly and swiftly, and make a large spread; see Isaiah 8:7. The Targum is,

"who is this that comes up with his army as a cloud, and covers the earth, and as a fountain of water, whose waters are moved?''

Who is this that cometh up as {f} a flood, whose waters are moved as the rivers?

(f) He derides the boastings of the Egyptians, who thought by their riches and power to have overcome all the world, alluding to the Nile river, which at certain times overflows the country of Egypt.

7. as a flood-(Jer 47:2; Isa 8:7, 8; Da 11:22). The figure is appropriate in addressing Egyptians, as the Nile, their great river, yearly overspreads their lands with a turbid, muddy flood. So their army, swelling with arrogance, shall overspread the region south of Euphrates; but it, like the Nile, shall retreat as fast as it advanced.

46:1-12 The whole word of God is against those who obey not the gospel of Christ; but it is for those, even of the Gentiles, who turn to Him. The prophecy begins with Egypt. Let them strengthen themselves with all the art and interest they have, yet it shall be all in vain. The wounds God inflicts on his enemies, cannot be healed by medicines. Power and prosperity soon pass from one to another in this changing world.
