C. F. Keil and Franz Delitzsch on Isaiah 26:10

Isa 26:10

Here again the shiir has struck the note of a mâshâl. And proceeding in this tone, it pauses here once more to reflect as at the close of a strophe. “If favour is shown to the wicked man, he does not learn righteousness; in the most upright land he acts wickedly, and has no eye for the majesty of Jehovah.” רשׁע יחן is a hypothetical clause, which is left to be indicated by the emphasis, like Neh 1:8 (Ewald, §357,b): granting that favour (chēn = “goodness,” Rom 2:4) is constantly shown to the wicked man. “The most upright land:” 'eretz necochoth is a land in which everything is right, and all goes honourably. A worthless man, supposing he were in such a land, would still act knavishly; and of the majesty of Jehovah, showing itself in passing punishments of sin, though still sparing him, he would have no perception whatever. The prophet utters this with a painful feeling of indignation; the word bal indicating denial with emotion.
