Charles Ellicott Commentary Isaiah 5:21

"Woe unto them that are wise in their own eyes, and prudent in their own sight!" — Isaiah 5:21 (ASV)

Woe unto them that are wise in their own eyes. —Here again the prophet would seem to have definite individual counsellors in his mind. For such men the ideal of statesmanship was a series of shifts and expedients, based upon no principle of righteousness. (Isaiah 30:1.)
