Hebrews 3:2

Who was faithful to him that appointed him The sacred penman, entering upon a comparison between Moses and Christ, as he was the apostle of God, or one sent by him to reveal his will, he recommends him to the faith of the Hebrews, under the principal qualification of a person in that office; he was faithful, which faithfulness he further describes by its respect to that act whereby he was appointed by God to the office. God's apostle is the chief steward or dispenser of his mysteries; and it is principally required in stewards that a man be found faithful. Now the fidelity of a legate, ambassador, or apostle consists principally in the full declaration of the mind and will of him who sent him, as to those ends for which he is sent. Faithfulness respects trust. Our Lord, therefore, must have had a trust committed to him wherein he was faithful. Accordingly he sought not his own glory, but the glory of him that sent him; declaring that he came not in his own, but in his Father's name, John 5:43. He moreover sealed that truth with his blood, which he came into the world to bear witness to, John 18:37; and greater faithfulness could not be expressed. As also Moses was faithful in all his house The church of Israel, then the peculiar family of God. The words are an allusion to the testimony which God bare to Moses, Numbers 12:7, My servant Moses is not so, who is faithful in all my house. It is true, Moses failed personally in his faith, and was charged of God that he believed him not, Numbers 20:12; but this was no impeachment of his faithfulness in the special office intended. As he was to reveal Jehovah's mind, and institute his worship, he was universally faithful; for according to all that God appointed him so did he, Exodus 40:16. He did not conceal any of the divine laws, on account of their disagreeableness to the Israelites; nor did he alter them in the least, to make them acceptable, but delivered the whole law as it was spoken to himself, and formed the tabernacle and the ritual of the worship exactly according to the pattern showed him. In like manner, Christ's faithfulness consisted in his teaching the doctrines, appointing the laws, and establishing the worship which his Father had ordained for the church.
