The story of God’s king — David. We remember the many chapters we read in 1 Samuel of all David’s troubles before he was made king. Here there is not a word about it.
V.1-3 For seven years David was king only in the town of Hebron and only king over Judah.
V.4-9 Then he was made king over all Israel in Jerusalem.
V.17-19 Notice that though there were some very powerful men, the “three mightiest” were doing David’s desire. All these men were rewarded according to their faithfulness to David. It is a good thing to remember that David is a shadow of Christ in a future day. The Lord Jesus is going to come back in power and victory to set up His kingdom (see your chart). Surrounding Him will be those who were faithful to Him during the day of tribulation.
