1 Samuel 22:14

Ahimelech said, Who is so faithful, &c. Or, rather, Who was so faithful, &c.; for it cannot be supposed, after Saul had just accused David of a conspiracy against him, that the high-priest would say he was then faithful. His apology, which sufficiently shows his innocence as to the things of which Saul accuses him, is, that since David had been held by all to be a most loyal subject, as well as a person of great honour, and in high favour with the king, having married his daughter, what could he think but that David was sent by the king, as he said he was, upon some business of public concern? Thus he does not take upon him to determine the difference between Saul and David, nor affirm what David now was; but only declares what David had formerly been, and what he was still, for any thing he knew to the contrary.
