The chapter opens with one long sentence. God spoke to the fathers many times and in many ways through the prophets, but in these last days he has spoken by his Son. God appointed this Son heir of all things and made the universe through him. The Son is the radiance of God's glory and the exact imprint of his nature, upholds all things by his powerful word and, after making purification for sins, sat down at the right hand of the Majesty on high.
From verse 4 on the author compares the Son with the angels. Because he is a Son, he has inherited a name more excellent than theirs. To prove it he cites a chain of Scriptures: God never said to an angel that he was his Son (Psalm 2) or that he would be his Father (2 Samuel 7); he commands the angels to worship the Son when he brings him into the world; and of the angels he says only that they are winds and flames of fire.
To the Son, however, he speaks in the language of throne and kingdom: his throne lasts forever, his scepter is a scepter of justice, and he has been anointed with the oil of gladness (Psalm 45). He is also the Lord who laid the foundations of the earth and who remains when the heavens wear out like a garment (Psalm 102). And only to him did God say to sit at his right hand until his enemies become a footstool for his feet (Psalm 110). The chapter ends with a question: are not the angels all ministering spirits sent out to serve those who are to inherit salvation?
