For You have made Your people Israel Your very own forever, and You, O LORD, have become their God.
David says the LORD has made Israel His own people forever and has become their God.
This verse states the lasting bond between the LORD and Israel.
16Then King David went in, sat before the LORD, and said, “Who am I, O LORD God, and what is my house, that You have brought me this far? 17And as if this was a small thing in Your eyes, O God, You have spoken about the future of the house of Your servant and have regarded me as a man of great distinction, O LORD God. 18What more can David say to You for honoring Your servant? For You know Your servant, 19O LORD. For the sake of Your servant and according to Your own heart, You have accomplished this great thing and made known all these great promises. 20O LORD, there is none like You, and there is no God but You, according to everything we have heard with our own ears. 21And who is like Your people Israel — the one nation on earth whom God went out to redeem as a people for Himself? You made a name for Yourself through great and awesome wonders by driving out nations from before Your people, whom You redeemed from Egypt. 22For You have made Your people Israel Your very own forever, and You, O LORD, have become their God. 23And now, O LORD, let the word You have spoken concerning Your servant and his house be established forever. Do as You have promised, 24so that Your name will be established and magnified forever when it is said, ‘The LORD of Hosts, the God of Israel, is God over Israel.’ And may the house of Your servant David be established before You. 25For You, my God, have revealed to Your servant that You will build a house for him. Therefore Your servant has found the courage to pray before You. 26And now, O LORD, You are God! And You have promised this goodness to Your servant. 27So now You have been pleased to bless the house of Your servant, that it may continue forever before You. For You, O LORD, have blessed it, and it will be blessed forever.”
