The installation of the king was a momentous event in the life of the nation, and David’s installation was the most momentous of them all. The man who killed Goliath, who was on run for years from Saul, who would be the epitome of kingship in Israel, but who would also sin greatly, was crowned as king! This day brought great rejoicing.
David united the people under one head. The nation stayed united under his son Solomon, but then fractured in two by Rehoboam and Jeroboam. Everyone looked back to David as the one who held it all together. This greatest king of the nation of Israel points forward to the greatest king of the universe, who unites all people.
David was a worthy king, but there is one who was and is more worthy. And they sang a new song, saying, “Worthy are you to take the scroll and to open its seals, for you were slain, and by your blood you ransomed people for God from every tribe and language and people and nation, and you have made them a kingdom and priests to our God, and they shall reign on the earth” (Revelation 5:9–10).
What does a king do? He reigns over his kingdom. He defeats his enemies. He leads and cares for his people. He receives glory and praise. The King of kings does just that for us. They will make war on the Lamb, and the Lamb will conquer them, for he is Lord of lords and King of kings, and those with him are called and chosen and faithful (Revelation 17:14). All his enemies will one day be made a footstool for his feet (Psalm 110:1) when he comes to reign again. Come quickly, Lord!
