For he flattereth himself in his own eyes, until his iniquity be found to be hateful.
Context
1 A revelation is within my heart about the disobedience of the wicked: There is no fear of God before his eyes.
2 For he flatters himself in his own eyes, too much to detect and hate his sin.
3 The words of his mouth are iniquity and deceit. He has ceased to be wise and to do good.
