Isaiah
Isaiah 26:10BSB·traditional attribution

Though grace is shown to the wicked man, he does not learn righteousness. In the land of righteousness he acts unjustly and fails to see the majesty of the LORD.

Jamieson-Fausset-Brown Reformed

uprightness--rather, as in Isa 26:7, "prosperity," answering to "favor" in the parallelism, and in antithesis to "judgments in the earth" (Isa 26:9); where prosperity attends the wicked as well as the just, "he will not learn righteousness," therefore judgments must be sent that he may "learn" it [MAURER].

John Calvin Reformed

10. The wicked man will obtain favour. {Bogus footnote} Isaiah contrasts this statement with the former. He had said that the godly, even when they are afflicted, or see others afflicted, still rely on the love of God, and trust in him.

Geneva Bible Notes Reformed

Let favour be shown to the wicked, [yet] he will not learn righteousness: in the land of uprightness he will deal unjustly, and will not behold the majesty of the LORD. (i) The wicked though God show them evident signs of his grace, will not be any better off.
