6. But Christ--was and is faithful (Heb 3:2).
      as a son over his own house--rather, "over His (GOD'S, Heb 3:4) house"; and therefore, as the inference from His being one with God, over His own house. So Heb 10:21, "having an High Priest over the house of God." Christ enters His Father's house as the Master [OVER it], but Moses as a servant [IN it, Heb 3:2, 5] [CHRYSOSTOM]. An ambassador in the absence of the king is very distinguished--in the presence of the king he falls back into the multitude [BENGEL].
      whose house are we--Paul and his Hebrew readers. One old manuscript, with Vulgate and LUCIFER, reads, "which house"; but the weightiest manuscripts support English Version reading.
      the rejoicing--rather, "the matter of rejoicing."
      of the hope--"of our hope." Since all our good things lie in hopes, we ought so to hold fast our hopes as already to rejoice, as though our hopes were realized [CHRYSOSTOM].
      firm unto the end--omitted in LUCIFER and AMBROSE, and in one oldest manuscript, but supported by most oldest manuscripts.
