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 thine heart, I am, and none else beside me.
For thou hast trusted in thy wickedness - referring, as in Isaiah 13:11, to the cruelty with which Babylon treated its subject states. Thou hast said, None seeth me (Psalms 10:11; Psalms 94:7) - 'There is none to exact punishment from me.' Sinners are not safe, though seeming secret.
Thy wisdom - astrological and political (Isaiah 19:11, etc., as to Egypt).
It hath perverted - turned thee aside from the right and safe path.
