2 Peter 1:17 - Matthew Poole's English Annotations on the Holy Bible

Either honour and glory for glorious honour; or glory may relate to that lustre which appeared in the body of Christ at his transfiguration, Matthew 17:2, and honour to the voice which came to him from his Father, and the honourable testimony thereby given him. From the excellent glory; either from heaven, or from the glorious God, the Father of Christ, who, by this voice, did in a special manner manifest his glorious presence. This is my beloved Son; i.e. This is the Messiah so often promised, and therefore all that was spoken of the Messiah in the law and the prophets centres in him. In whom I am well pleased: this implies not only that Christ is peculiarly the Beloved of the Father, but that all they that are adopted to God by faith in Christ, are beloved, and graciously accepted, in and through him, Matthew 3:17 1 Thessalonians 17:26 Ephesians 1:6.
