Psalms 45, 47-48, 87, 110
The first four of these psalms were penned by the sons of Korah, who were commissioned by David to serve and worship before the presence of God at David’s tabernacle on mount Zion (before the temple was constructed by Solomon). These are written in praise of the King, Who is the Lord, as well as the city of God, which is Jerusalem, and called mount Zion.
Psalm 110 was penned by David, and it is uniquely prophetic of Jesus, Who God has not only established as the King Who will rule forever, but Who has also been named as God’s High Priest, after the order of Melchizedek. The writer of Hebrews explains this in Hebrews 8, showing that the priestly order of Melchizedek was superior to Aaron, the first high priest in Israel, and that it will be only in Jesus that the office of King and Priest are united.
