Psalm 45:6 addresses the royal figure with extraordinary language: "Your throne, O God, is forever and ever," and describes the scepter of his kingdom as righteous. The precise relationship between the human king and this elevated language has prompted considerable interpretation, but the New Testament gives the verse an explicit Christological application.

Hebrews 1:8 quotes Psalm 45:6 while contrasting the Son with the angels: "But of the Son he says, 'Your throne, O God, is forever and ever.'" The author therefore applies the divine royal title and everlasting throne directly to Jesus. Whatever the psalm's original royal setting, Hebrews understands its language as reaching its full significance in the Son, whose kingship is eternal and whose rule is characterized by righteousness.
