2:1-8 The evil passions of the heart break out in various forms; but the Lord looks to our motives, as well as our conduct. Those that deal cruelly, shall be cruelly dealt with. Other nations were reckoned with for injuries done to men; Judah is reckoned with for dishonour done to God. Judah despised the law of the Lord; and he justly gave them up to strong delusion; nor was it any excuse for their sin, that they were the lies, the idols, after which their fathers walked.
