Charles Ellicott Commentary 1 Chronicles 17:14

"but I will settle him in my house and in my kingdom for ever; and his throne shall be established for ever." — 1 Chronicles 17:14 (ASV)

But I will settle him (Hebrew, make him stand) in my house and in my kingdom. —Samuel, and thine house and thy kingdom shall be maintained for ever before thee; thy throne, etc. where, however, the Septuagint and Syriac have before me, which agrees better with our text. The change of persons in our verse brings out more clearly the theocratic nature of the Davidic kingdom. Solomon and his successors were to reign as vicegerents of Jehovah.
