1 Kings 2:4
4. there shall not fail thee . . . a man on the throne of Israel—a reference to the promise made to David of the sovereignty being vested perpetually in his lineage (2Sa 7:11-16), which was confirmed to Solomon afterwards (see 1Ki 9:5), and repeated with reference to its spiritual meaning long after (Jer 33:17).
Psalms 89:4

with—or literally, "to" my chosen—as the covenant is in the form of a promise. Psalms 89:29
28-37. This relation is perpetual with David's descendants, as a whole typical in official position of his last greatest descendant. Hence though in personal relations any of them might be faithless and so punished, their typical relation shall continue. His oath confirms His promise, and the most enduring objects of earth and heaven illustrate its perpetual force (Ps 72:5, 7, 17).
