Jer 23:5  “The days are coming,” declares the LORD, “when I will raise up to David a righteous Branch, a King who will reign wisely and do what is just and right in the land.

Ps 89:35-36  Once for all, I have sworn by my holiness—and I will not lie to David—that his line will continue for ever and his throne endure before me like the sun;
