What did the royal line of David's house lead up to?
The royal line of David’s house led up to the coming of the King, the Christ, the Messiah. It would come down through Solomon on one side and Nathan on the other, yet the Davidic covenant promise looked ultimately to the Messiah’s arrival.
Les explains that II Samuel chapter 7 records the Davidic covenant, which God made with David concerning his offspring and the nation of Israel. The royal line of David’s house would lead up to the coming of the King, the Christ, the Messiah. Les notes that this line would come down through Solomon on one side and Nathan on the other. Though II Samuel 7:14 primarily addresses Solomon, God is looking at the long view of the whole nation of Israel. He would chasten Israel through enemy nations and other means when they fell into unbelief and abject behavior, but verse 15 begins with “But,” showing the flip side.
