Ethiopia and Egypt were her strength - Literally, "Egypt was strength , and Ethiopia, and boundless." He sets forth first the imperial might of No; then her strength from foreign, subdued power. The capital is a sort of impersonation of the might of the state; No, of Egypt, as Nineveh, of Assyria. When the head was cut off or the heart ceased to beat, all was lost. The might of Egypt and Ethiopia was the might of No, concentrated in her. They were strength, and that strength unmeasured by any human standard. Boundless was the strength, which Nineveh had subdued: boundless, the store Nahum 2:10 which she had accumulated for the spoiler; boundless Nahum 3:3 the carcasses of her slain. "And it was infinite." "The people that came up with the king out of Egypt, were without number" 2-Chronicles 12:3. The Egyptians connected with Thebes are counted by a pagan author at seven million. Put or Phut is mentioned third among the sons of Ham, after Cash anal Mizraim Genesis 10:6. They are mentioned with the Ethiopians in Pharaoh's army at the Euphrates , as joined with them in the visitation of Egypt Ezekiel 30:5; with Cush in the army of Gog Ezekiel 38:15; with Lud in that of Tyre Ezekiel 29:10; a country and river of that name were, Josephus tells us , "frequently mentioned by Greek historians." They dwelt in the Libya, conterminous to the Canopic mouth of the Nile .
And Lubim - These came up against Judah in the army of Shishak 2-Chronicles 12:3 against Rehoboam, and with the Ethiopians, "a huge host" under Zerah the Ethiopian against Asa . The Ribou or Libou appear on the monuments as a people conquered by Menephthes and Rameses III . They were still to be united with Egypt and the Ethiopians in the times of Antiochus Epiphanes Daniel 11:43; so their connection with Egypt was not broken by its fall. Those unwearied enemies had become incorporated with her; and were now her help. These were (English Margin) in thy help; set upon it, given up to it. The prophet appeals to No herself, as it were, "Thou hadst strength." Then he turns away, to speak of her, unwilling to look on the miseries which he has to portray to Nineveh, as the preludes of her own. Without God, vain is the help of man.

Ethiopia and Egypt were her strength - The land of Cush, not far from Diospolis; for it was in Arabia, on the Red Sea.
Put and Lubim - A part of Africa and Libya, which were all within reach of forming alliances with No-Ammon or Diospolis.

Ethiopia and Egypt were her strength,.... That is, the strength, support, protection, and defence of No, whether Alexandria, or Thebes, or Memphis: Egypt was, for these cities were in it, and subject to it; or, if this was a free city, as some think, yet in alliance with Egypt, and under its protection; and in like connection it was with Ethiopia, that is, Arabia, a country that lay near to it; and yet, though it was strengthened by such powerful neighbours and allies, it was not secure from the devastation of the enemy:
and it was infinite; or there was "no end" (o); of its strength, or of the number of its allies, or the forces they were able to bring in its defence. The Ethiopians were very numerous, as may be learnt from 2-Chronicles 14:9 and so were the Egyptians, to whom some interpreters strictly connect this sentence. In the times of Amasis, as Mela (p) relates, there were twenty thousand cities inhabited in it; and Josephus (q) says there were in it seven hundred and fifty myriads of men; as Sethon, king of Egypt, and Tirhakah, king of Ethiopia, were about this time the allies of the Jews, in whom they trusted, no doubt they were confederate together, and so both the strength of this city; see Isaiah 36:6,
Put and Lubim, were thy helpers; Put, or the Putim, were the people of the Moors, that dwelt in Mauritania; and Lubim were the Lybians that bordered on Egypt, and whose country is sometimes reckoned a part of it. The Jews (r) say Lybia is Egypt; see Acts 2:10 these several people were the confederates of No; and helped them, not only by their commerce with them, but in time of war assisted them against their enemies; and yet, though so strengthened by alliances, were not safe and secure; and therefore Nineveh could not depend upon such helps and helpers.

Ethiopia--Hebrew, Cush. Ethiopia is thought at this time to have been mistress of Upper Egypt.
Egypt--Lower Egypt.
her strength--her safeguard as an ally.
it was infinite--The resources of these, her allies, were endless.
Put--or Phut (Genesis 10:6); descended from Ham (Ezekiel 27:10). From a root meaning a bow; as they were famed as archers [GESENIUS]. Probably west of Lower Egypt. JOSEPHUS [Antiquities, 1:6.2] identifies it with Mauritania (compare Jeremiah 46:9, Margin; Ezekiel 38:5).
Lubim--the Libyans, whose capital was Cyrene; extending along the Mediterranean west of Egypt (2-Chronicles 12:3; 2-Chronicles 16:8; Acts 2:10). As, however, the Lubim are always connected with the Egyptians and Ethiopians, they are perhaps distinct from the Libyans. The Lubim were probably at first wandering tribes, who afterwards were settled under Carthage in the region of Cyrene, under the name Libyans.
thy--No's.
helpers--literally, "in thy help," that is, among thy auxiliaries.

Her strength - Furnishing soldiers and warlike assistance. It was infinite - There was no end to their confidence and warlike provisions. Put - Or the Moors, who lie westward of Alexandria. Lubim - The people that inhabited that which is now called Cyrene.
