Again, the prophet returns to Judah’s call to Egypt for help against the Assyrian invasion. What moved the prophet to address Judah’s leaders with a strong rebuke and biting satire was that their war planning not only ignored and factored God out of their plans, but that they also asked an idol-worshipping nation to be their help! Yahweh was passed over for the military of Egypt. The fact is that Egypt could only take Judah’s money, but did nothing to turn the Assyrian army away; Yahweh did that. Isaiah called Judah’s behavior sin.
