THE GOSPEL ACCORDING TO MATTHEW - Chapter 17 - Verse 5
When, therefore, the disciples saw this cloud, they were prepared to hear the word of the Lord.
This is my beloved Son. This was the voice of God. This was the second time that, in a remarkable manner, he had declared this. See Mt 3:17. This was spoken to confirm the disciples; to declare their duty to hear Christ rather than any other, and to honour him more than Moses and Elijah; and to strengthen their faith in him when they should go forth to preach the gospel, after he was shamefully put to death. After this, it was impossible for them to doubt that he was truly the Son of God. See 2 Pe 1:17,18.
{i} "voice" Mt 3:17; Mr 1:11; Lu 3:22; 2 Pe 1:17
{k} "in whom" Isaiah 42:1,21 {l} "hear ye" De 18:15,19; Ac 3:22,23; Hebrews 1:1,2; 2:1-3
