Jesus as the absolute ruler on earth will govern the Messianic Kingdom. His throne will be in Jerusalem. The government will be split into two branches, a Jewish branch and a Gentile branch. It is quite clear from both Testaments that Jesus will sit upon David’s Throne in Jerusalem ruling the Jews and Gentiles. For now, it is important to expand those passages that develop the Davidic Covenant and those that demonstrate that the Messiah will be a king over a literal physical kingdom.
Psalm 2:6-8
6Yet I have set my king Upon my holy hill of Zion. 7I will tell of the decree: Jehovah said unto me, Thou art my son; This day have I begotten thee. 8Ask of me, and I will give thee the nations for thine inheritance, And the uttermost parts of the earth for thy possession (ASV 1901).
