1 Kings 2:44-46

Revised Standard Version

⁴⁴ The king also said to Shim′e-i, “You know in your own heart all the evil that you did to David my father; so the Lord will bring back your evil upon your own head. ⁴⁵ But King Solomon shall be blessed, and the throne of David shall be established before the Lord for ever.” ⁴⁶ Then the king commanded Benai′ah the son of Jehoi′ada; and he went out and struck him down, and he died.

So the kingdom was established in the hand of Solomon.
