Charles Ellicott Commentary Isaiah 47:10

"For thou hast trusted in thy wickedness; thou hast said, None seeth me; thy wisdom and thy knowledge, it hath perverted thee, and thou hast said in thy heart, I am, and there is none else besides me." — Isaiah 47:10 (ASV)

For thou hast trusted in thy wickedness ... —Babylon, like other nations that have followed in her steps, took for its law that Might was Right, practically denied the existence of a Ruler who saw and judged, and boasted of its wisdom. The context implies that the special form of wisdom spoken of was that of astrology and magic.
