1 Chronicles 17:14

“I will settle him in my house--over My people Israel. and in my kingdom for ever--God here asserts His right of supreme sovereignty in Israel. David and Solomon, with their successors, were only the vicegerents whom He nominated, or, in His providence, permitted. his throne shall be established for evermore--The posterity of David inherited the throne in a long succession--but not always. In such a connection as this, the phrase "for evermore" is employed in a restricted sense (see on Lam 3:31).

“17:14 In the parallel at 2 Sam 7:16, God promises to establish David’s house, kingdom, and throne, whereas here it is Solomon’s. While the books of Samuel and Kings cast David as Israel’s ideal king, the Chronicler views Solomon as David’s equal. David made all the preparations for building the Temple, but God designated Solomon as the Temple builder. The promise to Israel was secured in the combined reigns of David and Solomon.”

“in mine: In the parallel passage, it is "thine house, and thy kingdom." Jehovah was Israel's king; and David and Solomon were merely his viceregents, as well as types of the Messiah. Psa 2:6, Psa 72:17, Psa 89:36; Luk 1:32, Luk 1:33; Heb 3:6 1 Chronicles 17:15”
