The word sknty, shekenti, is to be taken here for sknt, shekenet, a dweller; and the passage is more clear when we take it as the title of Babylon. And he says that she was a dweller among waters, because the Euphrates not only flowed by the city, (and we know that it was a very large river,) but it surrounded it; and it, was indeed divided above Babylon into many streams, so that it made as it were many islands, and thus access to the city was more difficult. This circumstance served not only for a defense to it, but also for other advantages.: For these streams or channels were navigable; and the land also was made more fertile by the irrigation they supplied. Thus these streams contributed to its wealth as well as to its defense in time of war. And though Babylon was deemed on this account impregnable, and was also a very fertile land, yet the Prophet says here that its end was come Now, except he had made this preface, that Babylon was situated among the rivers or many waters, and that it was also a city full of wealth, all this might have seemed a hindrance to prevent God from executing on it his vengeance; for this objection was ready at hand, "How can Babylon be taken, which is seated between many waters? for without great force and number of soldiers it cannot but remain in safety, since it is protected by so many rivers." Then another objection might have been brought forward, that Babylon was an opulent city, so that it could hire auxiliaries on every side, and that having such abundance of money, it would never be unprotected. Hence the Prophet here mentions these two things; but what he says ought to be taken adversatively, as if he said, "Though thou dwellest among many waters, and art great in treasures, that is, hast large treasures, yet thine end is come." He adds, the measure of thy cupidity. Some render 'mt, amet, "end," but improperly; and the Prophet has not without reason introduced the word 'mt, amet, which properly means a cubit, but is to be taken here for measure. Jerome renders it "a foot," a word in use in his age. But the meaning is sufficiently clear, that though Babylon had exhausted all the wealth of the world as an insatiable gulf, yet the measure of her cupidity would come. For the cupidity of that nation was unlimited, but God at length brought it to an end -- not that they were amended, but that God checked their coveting. And according to this sense the Prophet says, that though they had been hitherto devouring the wealth of many countries, yet the measure of her cupidity was come, even because the Lord would take away, together with the monarchy, the power and opportunity of doing wrong. For the Chaldeans were able to act licentiously, when they had so many nations subject to them; but the measure of their cupidity was come, when God in a manner cut off their strength, not that they then desisted, or that their rapacious disposition was amended -- for they changed not their nature; but cupidity is to be referred here to its exercise, even because their power was then taken from them, so that they could not carry on their plunders as they had used to do. He afterwards adds, --

Upon many waters - The great wealth of Babylonia was caused not merely by the Euphrates, but by a vast system of canals, which served for defense as well as for irrigation.
The measure of thy covetousness - i. e., the appointed end of thy gain. Some render it: the ell of thy cutting off, i. e., the appointed measure at which thou art to be cut off, at which thy web of existence is to be severed from the loom.

O thou that dwellest upon many waters - Thou who hast an abundant supply of waters. It was built on the confluence of the Tigris and Euphrates; the latter running through the city. But the many waters may mean the many nations which belonged to the Babylonish empire; nations and people are frequently so called in Scripture.

O thou that dwellest upon many (i) waters, abundant in treasures, thy end is come, [and] the measure of thy covetousness.
(i) For the land of Chaldea was full of rivers which ran into the Euphrates.

O thou that dwellest upon many waters,.... Here Babylon is addressed, either by the Lord, or by the prophet, or the godly Jews; who is described by her, situation, which was by the great river Euphrates; which being branched out into several canals or rivers, both ran through it, and encompassed it; hence mention is made of the rivers of Babylon, Psalm 137:1; and a fit emblem this city was of mystical Babylon, which is also said to sit on many waters, interpreted of people and nations, Revelation 17:1; and which Kimchi here interprets of an affluence of good things, though he admits of the literal sense of the words:
abundant in treasures: of corn, and of the fruits of the earth, and so in condition to hold out a siege, as well as strongly fortified by art and nature, before described; and of gold and silver, the sinews of war, which she had got together, partly by commerce, and partly by the spoil of other nations; and yet neither her situation nor her affluence could secure her from ruin:
thine end is come, and the measure of thy covetousness; this flourishing city was now near its end, and with it the whole Babylonish monarchy; the time fixed by the Lord, for the duration of one and the other, was now come; and whereas her covetousness was insatiable, and would have known no bounds, for the enlargement of her dominions, and for the accumulation of more wealth and riches; God set a limit to it, beyond which it should not go; which measure was now filled up, and the time for it expired. The Targum is,
"the day of thy destruction is come, and the time of the visitation of thy wickedness,''

waters-- (Jeremiah 51:32, Jeremiah 51:36; see on Isaiah 21:1). The Euphrates surrounded the city and, being divided into many channels, formed islands. Compare as to spiritual Babylon "waters," that is, "many peoples," Revelation 17:1, Revelation 17:15. A large lake also was near Babylon.
measure--literally, "cubit," which was the most common measure, and therefore is used for a measure in general. The time for putting a limit to thy covetousness [GESENIUS]. There is no "and" in the Hebrew: translate, "thine end, the retribution for thy covetousness" [GROTIUS]. MAURER takes the image to be from weaving: "the cubit where thou art to be cut off"; for the web is cut off, when the required number of cubits is completed (Isaiah 38:12).

All the supports of the Babylonian power, its strong position on the Euphrates, and its treasures, which furnished the means for erecting strong fortifications, cannot avert the ruin decreed by God. As to the form שׁכנתּי, see on Jeremiah 22:23. It is the city with its inhabitants that is addressed, personified as a virgin or daughter. The many waters on which Babylon dwells are the Euphrates, with the canals, trenches, dykes, and marches which surrounded Babylon, and afforded her a strong protection against hostile attacks, but at the same time contributed to increase the wealth of the country and the capital.
(Note: Duncker, Gesch. d. Alterth. i. S. 846, remarks: "The fertility of the soil of Babylon - the produce of the fields - depended on the inundations of the Euphrates. By means of an extensive system of dykes, canals, and river-walls, Nebuchadnezzar succeeded not only in conducting the water of the Euphrates to every point in the plain of Babylon, but also in averting the formation of marshes and the occurrence of floods (which were not rare), as well as regulating the inundation." The purpose for which these water-works were constructed, was "first of all, irrigation and navigation; but they at the same time afforded strong liens of defence against the foe" (Niebuhr, Gesch. Assyr. u. Bab. S. 219). See details regarding these magnificent works in Duncker, S. 845ff.; Niebuhr, S. 218ff.)
The great riches, however, by which Babylon became רבּת אוצרות, "great in treasures," so that Aeschylus (Pers. 52) calls it Βαβυλῶν ἡ πολύχρυσος, were derived from the enormous spoils which Nebuchadnezzar brought to it, partly from Nineveh, partly from Jerusalem, and from the tribute paid by Syria and the wealthy commercial cities of Phoenicia. "Thine end is come;" cf. Genesis 6:13. אמּת בּצעך, "the ell (i.e., the measure) of thy gain," i.e., the limit put to thine unjust gain. The words are connected with "thine end is come" by zeugma. This explanation is simpler than the interpretation adopted by Venema, Eichhorn, and Maurer, from the Vulgate pedalis praecisionis tuae, viz., "the ell of cutting thee off." Bttcher (Proben, S. 289, note m) seeks to vindicate the rendering in the following paraphrase: "The ell at which thou shalt be cut off, like something woven or spun, when it has reached the destined number of ells." According to this view, "ell" would stand for the complete number of the ells determined on; but there is no consideration of the question whether בּצע, "to cut off the thread of life," Isaiah 38:12, can be applied to a city.

Waters - Babylon is said to dwell upon many waters, because the great river Euphrates, did not only run by it, but almost encompass it branching itself into many smaller rivers, which made several parts of the city, islands.
