“Your throne, O God, is forever and ever; A scepter of uprightness is the scepter of Your kingdom.”
-This text is thought to refer to Jesus, perhaps because it is quoted and applied to Jesus in Heb. 1:8.
-The psalm seems to be referring to one of the Davidic kings who is married and with children (cf. 45:9-11, 13-14). The most likely application for this psalm is arguably Solomon, but Jesus certainly does not have a wife or virgin daughters.
-Therefore, the Davidic king, who is promised an eternal throne (cf. 2 Sam. 7:13, 16), is addressed by the psalmist as God. The very next verse (45:7) says that, “Therefore God, Your God, has anointed You With the oil of joy.” The Davidic king has a God who is his superior.
-The title God is in this psalm used in two different senses. In 45:6 it is used of the king, clearly in a representative sense. The king is ruling on God’s behalf and can therefore be given the title through the principle of agency. The Davidic king’s God (45:7) is the one true God who has anointed the king with oil.
-Some translations (NAB) recognize the different ways in which elohim is used in the psalm by differentiating the two individuals. The king is “god” (lowercase) while his God is “God” (uppercase).
