What does Isaiah 19:13 mean?
Isaiah's prophecy (Isaiah 19:1) is dismantling the myth that Egypt could be a strong and unbeatable ally. Israel would have been tempted to make alliances in fear of invaders. Yet, whether against the Assyrians or the Babylonians, Egypt was like any other nation: owing any success it has to the Lord. They are also just as subject to the Lord's judgment. When that happens, the Egyptian people will lose their courage and turn on each other (Isaiah 19:2). They will turn to occult practices to look for answers (Isaiah 19:3). A fierce king will swoop in and take over the country (Isaiah 19:4). The Lord will dry up the Nile, dismantling the entire Egyptian economy in the process (Isaiah 19:5–10).Now the prophet has added that, against the wisdom and power of God, the best and brightest of Egypt's wise men are half-witted. The "princes" mentioned here would be leaders giving direct counsel and advice to the Pharaoh. They cannot provide a single clue about God's plans against them (Isaiah 19:11–12). The princes in the important cities of Zoan and Memphis may think they are geniuses, but measured against God's judgment they are "deluded" fools. When the leadership of the nation is clueless, the entire nation will stagger and begin to disintegrate. Isaiah has said that's exactly what is coming for Egypt.
