'Iniquity' in the Bible

And it is displeasing to Abner exceedingly, because of the words of Ish-Bosheth, and he saith, 'The head of a dog am I -- that in reference to Judah to-day I do kindness with the house of Saul thy father, unto his brethren, and unto his friends, and have not delivered thee into the hand of David -- that thou chargest against me iniquity concerning the woman to-day?

And the woman of Tekoah saith unto the king, 'On me, my lord, O king, is the iniquity, and on the house of my father; and the king and his throne are innocent.'

And Absalom saith unto Joab, 'Lo, I sent unto thee, saying, Come hither, and I send thee unto the king to say, Why have I come in from Geshur? -- good for me while I am there -- and now, let me see the king's face, and if there is in me iniquity then thou hast put me to death.'

and saith unto the king, 'Let not my lord impute to me iniquity; neither do thou remember that which thy servant did perversely in the day that my lord the king went out from Jerusalem, -- for the king to set it unto his heart;

And I am perfect before Him, And I keep myself from mine iniquity.

And the heart of David smiteth him, after that he hath numbered the people, and David saith unto Jehovah, 'I have sinned greatly in that which I have done, and now, O Jehovah, cause to pass away, I pray Thee, the iniquity of Thy servant, for I have acted very foolishly.'
