Jeremiah 46:8

8 Egypt ascended at the likeness of a flood, and his waves shall be moved as [the] floods; and it shall say, I shall ascend, and cover the earth; I shall lose the city, and (the) dwellers thereof. (It is Egypt that goeth up like a flood, yea, like a river overflowing its banks; and it shall say, I shall rise, and cover the earth; I shall destroy the city, and its inhabitants.)

Jeremiah 46:8 Meaning and Commentary

Jeremiah 46:8

Egypt riseth up as a flood, and [his] waters are moved like the
rivers
This is the answer to the above question; that it was Egypt that was seen; the king of Egypt, as the Syriac version; he with his army, as the Targum; and which was so numerous, that it seemed as if the whole country of Egypt, all the inhabitants of it, were come along with him; these rose up like the Nile, and moved like the several sluices of it, with great velocity and force, as if they would carry all before them: and he saith, I will go up;
Pharaohnecho king of Egypt said, I will go up from my own land to the north, to meet the king of Babylon: [and] will cover the earth;
with his army: even all, the north country, the whole Babylonish empire; which he affected to be master of, grasping at, universal monarchy: I will destroy the city, and the inhabitants thereof;
which Abarbinel restrains to the city Carchemish, where his army was smitten: but it is better to interpret, the singular by the plural, as the Targum does, "I will destroy cities"; since it was not a single city he came up to take, nor would this satisfy his ambitious temper.

Jeremiah 46:8 In-Context

6 A swift man shall not flee, and a strong man guess not himself to be saved; at the north, beside the flood [of] Euphrates, they were overcome, and fell down. (But the swift shall not be able to flee away, and the strong shall not be able to save themselves; in the north, by the Euphrates River, they were overcome, and fell down.)

7 Who is this, that ascendeth as a flood, and his swells waxed great as of floods? (Who is this, who goeth up like a flood, yea, like a river overflowing its banks?)

8 Egypt ascended at the likeness of a flood, and his waves shall be moved as [the] floods; and it shall say, I shall ascend, and cover the earth; I shall lose the city, and (the) dwellers thereof. (It is Egypt that goeth up like a flood, yea, like a river overflowing its banks; and it shall say, I shall rise, and cover the earth; I shall destroy the city, and its inhabitants.)

9 Ascend ye upon horses, and make ye full out joy in chariots (Go ye upon horses, and rejoice, or shout, ye in the chariots); and strong men, come forth, Ethiopia and Libya, holding shield, and Lydia, taking and shooting arrows.

10 Forsooth that day of the Lord God of hosts is a day of vengeance, that he take vengeance of his enemies; the sword shall devour, and shall be [full-]filled, and shall greatly be filled with the blood of them; for why the slain sacrifice of the Lord of hosts is in the land of the north, beside the flood [of] Euphrates. (For that day of the Lord God of hosts is a day of vengeance, that he take vengeance on his enemies; the sword shall devour, and shall be filled full, yea, it shall be greatly filled with their blood; for the slain sacrifice of the Lord of hosts is in the land of the north, by the Euphrates River.)
