Hebrews 1:8

“But unto the Son, he saith, etc..] What he does not to angels, and which sets him infinitely above them; which shows him to be a Prince and King, and not a servant, or minister; and which even ascribes deity to him: thy throne, O God, is for ever and ever: this, with what follows in this verse, and the next, is taken out of (<194506>Psalm 45:6,7) which psalm is not spoken of Solomon, to whom many things in it will not agree; he was not fairer than other men; nor was he a warrior; nor was his throne for ever and ever; and much less a divine person, and the object of worship; but the Messiah, and so the ancient Jews understand it: the Targum applies it to him, and mentions him by name in…”

“1:8-9 These verses, quoting Ps 45:6-7, proclaim the Son as the divine, just, eternal, anointed King of the universe. • to the Son he says: Jesus is addressed as God; in Heb 1:9, your God is a reference to God the Father. • pouring out the oil of joy: Olive oil was used to anoint kings of Israel at the inauguration of their rule (1 Sam 10:1; 1 Kgs 19:15-16). God has anointed his Son, Jesus Christ, as King.”
