2 Samuel 7:16-19

16Your house (royal dynasty) and your kingdom will endure forever before Me; your throne will be established forever.” ’ ”

17Nathan spoke to David in accordance with all these words and all of this vision.

18Then King David went in and sat [in prayer] before the Lord, and said, “Who am I, O Lord God, and what is my house (family), that You have brought me this far?

19Yet this was very insignificant in Your eyes, O Lord God, for You have spoken also of Your servant’s house (royal dynasty) in the distant future. And this is the law and custom of man, O Lord God.
