Hebrews 3:2

Intending to depict the advantages of Christ over Moses, the apostle speaks about the high priesthood and says that both the one and the other were entrusted with the people, but Christ to a greater degree. At first he does not show the superiority of …

Who was, or is faithful, etc. This is a commendation of the apostleship of Christ, in order that the faithful may securely acquiesce in him; and he commends it on two grounds, because the Father has set him to be over us as our teacher, and because Christ himself has faithfully performed the office committed to him.

(3.) That he is as faithful to him that appointed him as Moses was in all his house. Moses was faithful in the discharge of his office to the Jewish church in the Old Testament, and so is Christ under the New; this was a proper argument to urge upon the Jews, who had so high an opinion of the faithfulness of Moses, and yet his faithfulness was but typical of Christ's.

Who was faithful to him - In Num 12:7, God gives this testimony to Moses: My servant Moses - is faithful in all my house; and to this testimony the apostle alludes. House not only means the place where a family dwells, but also the family itself.

Who was faithful--The Greek implies also that He still is faithful, namely, as our mediating High Priest, faithful to the trust God has assigned Him (Heb 2:17). So Moses in God's house (Nu 12:7). appointed him--"made Him" HIGH PRIEST; to be supplied from the preceding context. Greek, "made"; so in Heb 5:5;

Who was faithful - see the note, Heb 2:17. He performed with fidelity all the functions entrusted to him. To him that appointed him - Margin, “made.” The word “made,” however, is used in the sense of constituted, or appointed. The meaning is, that he was faithful to God. Perhaps Paul urges on them the necessity of considering “his fidelity” in order to keep “them” from the danger of apostasy. A leading object of this Epistle was to preserve those whom he had addressed from apostatizing from God amidst the temptations and trials to which they were exposed. In doing this, what could be a more powerful argument than to direct their attention to the unwavering constancy and fidelity of the Lord Jesus? The “importance” of such a virtue in the Saviour is manifest. It is seen everywhere; and all the great interests of the world depend on it. A husband should maintain inviolate fidelity toward a wife, and a wife toward her husband; a child should be faithful to a parent, a clerk and apprentice to his employer, a lawyer to his client, a physician to his patient, an ambassador to the government that commissions him. No matter what may be the temptations in the way, in all these, and in all other relations, there should be inviolate fidelity. The welfare of the world depended on the faithfulness of the Lord Jesus. Had he failed in that, all would have been lost. His fidelity was worthy of the more attentive consideration from the numerous temptations which beset his path, and the attempts which were made to turn him aside from his devotedness to God. Amidst all the temptations of the adversary, and all the trials through which he passed, he never for a moment swerved from fidelity to the great trust which had been committed to his hands. What better example to preserve them from the temptations to apostasy could the apostle propose to the Christians whom he addressed? […]
