Hebrews 3:2; Hebrews 3:5-6

2 He was faithful to the one who appointed him, just as Moses was faithful in all God's house.
5 Moses was faithful as a servant in all God's house, testifying to what would be said in the future. 6 But Christ is faithful as a son over God's house. And we are his house, if we hold on to our courage and the hope of which we boast.
