Isaiah 30:15

The second, more specific reason for Judah’s coming judgment (cf. Isaiah 30:9), was her refusal to listen to a particular message from the sovereign Lord her God, the Holy One of Israel. Isaiah had called the people to repent and rest in the Lord for their salvation. He had promised that their quiet trust in Him would prove to be their strength (cf. Isaiah 7:4; Isaiah 7:10-12; Isaiah 28:12). He had commanded "not alliance but reliance." [Note: G. A. Smith, The Book of Isaiah , 1:128.] Yet the people refused to obey.
