NET
10 You were complacent in your evil deeds; you thought, ‘No one sees me.’ Your self-professed wisdom and knowledge lead you astray, when you say, ‘I am unique! No one can compare to me!’
Darby
10 For thou hast confided in thy wickedness: thou hast said, None seeth me. Thy wisdom and thy knowledge, it hath seduced thee; and thou hast said in thy heart, It is I, and there is none but me.
KJV
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 thine heart, I [am], and none else beside me.
