2 Samuel 7:12-19

When your days are fulfilled and you lie down [in death] with your fathers (ancestors), I will raise up your descendant after you, who shall be born to you, and I will establish his kingdom. He [is the one who] shall build a house for My Name and My Presence, and I will establish the throne of his kingdom forever. I will be his Father, and he shall be My son. When he commits iniquity (wrongdoing), I will discipline him with the rod of men and with the strokes of the sons of man. But My lovingkindness and mercy will not depart from him, as I took it from Saul, whom I removed from before you. Your house (royal dynasty) and your kingdom will endure forever before Me; your throne will be established forever.” ’ ” Nathan spoke to David in accordance with all these words and all of this vision. Then 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? Yet 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.
