1 Samuel 22:10

He inquired of the Lord for him Some think Doeg slandered Ahimelech in this, because we read nothing of it in the foregoing chapter; and David in the Psalms speaks of his false tongue. But whether or not, he was guilty of great wickedness in concealing part of the truth, which in this case he ought to have declared, for Ahimelech's just defence; namely, the artifice whereby David had deceived him, making him believe that he was going on the king's business; so that the service which Ahimelech did to David was designed in honour of Saul. And gave him victuals, &c. Very innocently, as Doeg very well knew. But he represented these as acts whereby Ahimelech had aided and abetted David in a conspiracy; which are the lies that David lays to his charge, nothing being further from the truth.
