Isaiah 30:1

Yahweh pronounced woe on the Judahites who were acting like rebellious children (cf. Isaiah 1:2; Deuteronomy 21:18-21). They were carrying out a plan that was not the Lord’s. Specifically they were seeking an alliance with Egypt. Yahweh had forbidden alliances with Egypt (Exodus 13:17; Deuteronomy 17:16). These Judahites added to the sin of acting without divine direction, the sin of seeking security from a source other than the Lord Himself.
