*45:1 Jesus spoke of what was written of Him “in the Psalms” (see Luke 24:44). This is one such Messianic psalm; however, the capitalization indicating the deity is provided with the understanding that the chapter is written against the background of an ordinary royal wedding with anonymous participants. The New Testament reference to this psalm is in Heb 1:8, 9, where vv 6, 7 is quoted and applied to Christ. The preceding verses could also be applied to Christ, as well as most of the following verses referring to the King. However, v 16 can only apply to a mortal king (see note there).
†45:6 This verse has mystified many commentators since God is distinguished from the King in vv 2 and 7, and various translations have been proposed to make the Hebrew rendered “O God” something other than a reference to the deity of the King. But the writer of Hebrews clearly understood it this way.
‡45:16 Unlike the other references to the King, this verse cannot be applied prophetically to Christ because He had no children. But it is not unusual for a prophecy to have more than one fulfillment (typically in the near future of the prophecy and another in the distant future), and by analogy there is no reason why this psalm cannot refer both to an ordinary king and to the future Messianic King.
