Isaiah, Chapter 22, verses 19-23
15 He prophesieth Shebna's deprivation, 20 and Eliakim prefiguring the kingdom of Christ, his substitution11
11:33 O the depth of the riches, and wisdom, and knowledge of God - In the ninth chapter, St. Paul had sailed but in a narrow sea: now he is in the ocean.The depth of the riches is described, Rom 11:35;
the depth of wisdom, Rom 11:34;
the depth of knowledge, in the latter part of this verse.Wisdom directs all things to the best end; knowledge sees that end.How unsearchable are his judgments - With regard to unbelievers.His ways - With regard to believers.His ways are more upon a level; His judgments "a great deep." But even his ways we cannot trace.
11:34 Who hath known the mind of the Lord - Before or any farther than he has revealed it. Isa 40:13.
11:35 Given to him - Either wisdom or power?
11:36 Of him - As the Creator. Through him - As the Preserver. To him - As the ultimate end, are all things.To him be the glory of his riches, wisdom, knowledge.Amen - A concluding word, in which the affection of the apostle, when it is come to the height, shuts up all.
Matthew, Chapter 16, verses 13-20
13 The people's opinion of Christ, 16 and Peter's confession of him16
16:13 And Jesus coming - There was a large interval of time between what has been related, and what follows. The passages that follow were but a short time before our Lord suffered. Mar 8:27; Luk 9:18.
16:14 Jeremiah, or one of the prophets - There was at that time a current tradition among the Jews, that either Jeremiah, or some other of the ancient prophets would rise again before the Messiah came.
16:16 Peter - Who was generally the most forward to speak.
16:17 Flesh and blood - That is, thy own reason, or any natural power whatsoever.
16:18 On this rock - Alluding to his name, which signifies a rock, namely, the faith which thou hast now professed; I will build my Church - But perhaps when our Lord uttered these words, he pointed to himself, in like manner as when he said, Destroy this temple, Joh 2:19; meaning the temple of his body. And it is certain,that as he is spoken of in Scripture, as the only foundation of the Church, so this is that which the apostles and evangelists laid in their preaching. It is in respect of laying this, that the names of the twelve apostles (not of St. Peter only) were equally inscribed on the twelve foundations of the city of God, Rev 21:14.The gates of hell - As gates and walls were the strength of cities, and as courts of judicature were held in their gates, this phrase properly signifies the power and policy of Satan and his instruments.Shall not prevail against it - Not against the Church universal, so as to destroy it. And they never did. There hath been a small remnant in all ages.
16:19 I will give thee the keys of the kingdom of heaven - Indeed not to him alone, (for they were equally given to all the apostles at the same time, Joh 20:21-23) but to him were first given the keys both of doctrine and discipline. He first, after our Lord's resurrection, exercised the apostleship, Act 1:15. And he first by preaching opened the kingdom ofheaven, both to the Jews, Act 2:14etc , and to the Gentiles, Act 10:34etc Under the term of binding and loosing are contained all thoseacts of discipline which Peter and his brethren performed as apostles: and undoubtedly what they thus performed on earth, God confirmed in heaven. Mat 18:18.
16:20 Then charged he his disciples to tell no one that he was the Christ - Jesus himself had not said it expressly even to his apostles, but left them tb infer it from his doctrine and miracles. Neither was it proper the apostles should say this openly, before that grand proof of it, his resurrection. If they had, they who believed them would the more earnestly have sought to take and make him a king: and they who did not believe them would the snore vehemently have rejected and opposed such a Messiah.

By the Persians, Medes, and Assyrians, Isa 22:6-7.

22:23 Fasten - I will establish the power in his hands.Sure place - In the strong walls, or solid timber, in the house.He shall be - By his prudent and righteous government he shall procure great glory, to all that have any relation to him.
