Isaiah 19:2

“And I will set the Egyptians against the Egyptians, &c.] Or mingle and confound them together; in which confusion they should fall upon and destroy one another, as the Midianites did: the phrase is expressive of rebellions and civil wars, as the following words explain it; and which show, that the calamities of Egypt should be brought upon them, not by means of a foreign invasion, but by internal quarrels, and other means, which the Lord would in judgment send among them: and they shall fight everyone against his brother, and everyone against his neighbour; and destroy one another: city against city; of which there were great numbers in Egypt; in the times of Amasis, it is saidf360, there…”

“set--stir up. GESENIUS translates, "arm." Egyptians against the Egyptians--Lower against Upper: and Saitic against both. (See Isa 3:10). NEWTON refers it to the civil wars between Apries and Amasis at the time of Nebuchadnezzar's invasion; also between Tachos, Nectanebus, and the Mendesians, just before Ochus subdued Egypt. kingdom against kingdom--The Septuagint has "nome against nome"; Egypt was divided into forty-two nomes or districts.”

“And I will set - (סכסכתי sı̂ksaketı̂y). This word (from סכך sākak) means properly “to cover,” to spread over, to hide, conceal, to protect. Another signification of the verb is, to weave, to intermingle. It may mean here, ‘I will arm the Egyptians against each other’ (Gesenius); or, as in our version, ‘I will mingle, confound, or throw them into discord and strife.’ The Septuagint renders it, Ἐπεγερθήσονται Epegerthēsontai - ‘They shall be excited,’ or, ‘raised up.’ Symmachus, Συμβαλῶ Sumbalō. Syriac and Chaldee, ‘I will excite.’ The sense is, that there would be discord and civil war, and this is traced to the agency or overruling providence of God - meaning that he would “permit and…”

“I will set - Egypt was now one kingdom, but not many years after this time it was divided into twelve kingdoms, between whom there were many and cruel wars. Isaiah 19:3”

“19:2 Egypt had a history of civil wars that ravaged the country. Egypt’s fragile unity was breaking apart.”

“I will: Isa 19:13, Isa 19:14, Isa 9:21; Jdg 7:22, Jdg 9:23; Sa1 14:16, Sa1 14:20; Ch2 20:22, Ch2 20:23; Eze 38:21; Mat 12:25; Rev 17:12-17 set: Heb. mingle Isaiah 19:3”

“"And I spur Egypt against Egypt: and they go to war, every one with his brother, and every one with his neighbour; city against city, kingdom against kingdom. And the spirit of Egypt is emptied out within it: and I swallow up its ready counsel; and they go to the idols to inquire, and to the mutterers, and to the oracle-spirits, and to the soothsayers. And I shut up Egypt in the hand of a hard rule; and a fierce king will reign over them, saith the Lord, Jehovah of hosts." Civil war will rage in Egypt (on sicsēc, see at Isa 9:10). The people once so shrewd are now at their wits' end; their spirit is quite poured out נבקה, with the reduplication removed, for נבקּה, according to Ges. 68, Anm.…”
