Are righteous and very faithful - Margin, as in Hebrew, “righteousness and faithfulness.” They are “so” righteous, and so deserving of confidence - so certain to be accomplished, and so worthy to be trusted in - that they may be spoken of as “righteousness” and “fidelity” of the most perfect kind; the very essence of that which is right.
