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" ; 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 2Ch 14:9 and so were the Egyptians, to whom some interpreters strictly connect this sentence. In the times of Amasis, as Mela relates, there were twenty thousand cities inhabited in it; and Josephus 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 Isa 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 say Lybia is Egypt; see Ac 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.
