Wo unto the wicked - To all the wicked - but here having particular reference to the Jews whom Isaiah was addressing.
It shall be ill with him - The word “ill” is the only word here in the original. It is an emphatic mode of speaking - expressing deep abhorrence and suddenness of denunciation. ‘Woe to the impious! Ill!’
For the reward of his hands - Of his conduct. The hands are the instruments by which we accomplish anything, and hence, they are put for the whole man.
Shall be given him - That is, shall be repaid to him; or he shall be justly recompensed for his crimes. This is the principle on which God rules the world. It shall be well here and hereafter, with those who obey God; it shall be ill here and forever, with those who disobey him.
