The Messiah was to be of the line of David, and therefore many thought he would be more than David and the Judges combined, and would being an eternal Kingdom of the Jews. They miss a few points. The kingdom of Solomon was divided, and then the thrones of Israel and Judah were extinguished by the Assyrians and Babylonians. There was no king in the time of David who was Jewish: Herod was a Nabatean Puppet.
And Nathan said that this Son of David would suffer stripes “from the sons of men”. He would be rejected. His kingdom would not end, for it was not a kingdom of this world.
And by the very punishment he bore for us we are healed indeed.
7 Now when the king lived in his house and the Lord had given him rest from all his surrounding enemies, 2 the king said to Nathan the prophet, “See now, I dwell in a house of cedar, but the ark of God dwells in a tent.” 3 And Nathan said to the king, “Go, do all that is in your heart, for the Lord is with you.”
4 But that same night the word of the Lord came to Nathan, 5 “Go and tell my servant David, ‘Thus says the Lord: Would you build me a house to dwell in? 6 I have not lived in a house since the day I brought up the people of Israel from Egypt to this day, but I have been moving about in a tent for my dwelling. 7 In all places where I have moved with all the people of Israel, did I speak a word with any of the judges of Israel, whom I commanded to shepherd my people Israel, saying, “Why have you not built me a house of cedar?”’ 8 Now, therefore, thus you shall say to my servant David, ‘Thus says the Lord of hosts, I took you from the pasture, from following the sheep, that you should be prince over my people Israel. 9 And I have been with you wherever you went and have cut off all your enemies from before you. And I will make for you a great name, like the name of the great ones of the earth. 10 And I will appoint a place for my people Israel and will plant them, so that they may dwell in their own place and be disturbed no more. And violent men shall afflict them no more, as formerly, 11 from the time that I appointed judges over my people Israel. And I will give you rest from all your enemies. Moreover, the Lord declares to you that the Lord will make you a house. 12 When your days are fulfilled and you lie down with your fathers, I will raise up your offspring after you, who shall come from your body, and I will establish his kingdom. 13 He shall build a house for my name, and I will establish the throne of his kingdom for ever. 14 I will be to him a father, and he shall be to me a son. When he commits iniquity, I will discipline him with the rod of men, with the stripes of the sons of men, 15 but my steadfast love will not depart from him, as I took it from Saul, whom I put away from before you. 16 And your house and your kingdom shall be made sure for ever before me. Your throne shall be established for ever.’” 17 In accordance with all these words, and in accordance with all this vision, Nathan spoke to David.
