A primary concern of the Chronicler, the evidence of which is his selection of material and emphases, was the promise of a King who would eventually come and rule over God's people. God had fulfilled some of the Davidic Covenant promises in David's lifetime. He fulfilled others in Solomon's reign. Still others remained unfulfilled. For a third time the writer recorded the promises God gave to David. In the first case, God spoke to David (17:1-27). In the second, David spoke to Solomon (22:1-19). In the third, David spoke to Solomon and Israel's other leaders (28:1).
David may have thought Solomon would fulfill the rest of the promises in the covenant (28:5-7). He must have realized that to do so Solomon would have to obey God faithfully (28:7). Solomon, however, was not completely obedient. Consequently if God is faithful to His promises, a faithful Son of David had to arise. The Chronicler looked forward to this future hope.
In describing David's plans for building the temple the Chronicler seems to have wanted to present David as a second Moses. He also seems to have wanted to present Solomon as a second Joshua to some extent.79
