Prophet, Priest and King
The three offices of prophet, priest and king are only occupied by the Lord Jesus Christ as a complete set.
David was a king and a prophet, 1 Samuel 17.13; Acts 2.31.
Ezekiel was a priest and a prophet, Ezekiel 1.3.
Uzziah tried to combine kingship and priesthood which led to God punishing him by making him a leper, 2 Chronicles 26.16-23. Only the Lord Jesus can rightly combine both offices, Zechariah 6.13.
Christ is a
Great King, Psalm 48.2; Matthew 5.35.
Great Prophet, Luke 7.16.
Great High Priest, Hebrews 4.14. Aaron was only a high priest.
