Psalms 89:26-29

God promised that David would enjoy a special relationship of intimacy with Yahweh, who would treat him as His firstborn son (2 Samuel 7:14). This involved double blessings and much authority under his Father. David would become the most highly exalted king on the earth. Moreover, God would bless him with a dynasty that would rule Israel forever (cf. 2 Samuel 7:12-13; 2 Samuel 7:16).
