2nd Samuel 7:18

15 But my mercy shall not depart away from him, as I took it from Saul, whom I put away before thee.

16 And thine house and thy kingdom shall be established for ever before thee: thy throne shall be established for ever.

17 According to all these words, and according to all this vision, so did Nathan speak unto David.

18 Then went king David in, and sat before the LORD, and he said, Who am I, O Lord GOD? and what is my house, that thou hast brought me hitherto?

19 And this was yet a small thing in thy sight, O Lord GOD; but thou hast spoken also of thy servant's house for a great while to come. And is this the manner of man, O Lord GOD?

20 And what can David say more unto thee? for thou, Lord GOD, knowest thy servant.

21 For thy word's sake, and according to thine own heart, hast thou done all these great things, to make thy servant know them.
