David assembled all the princes of Israel, the princes of the tribes, and the captains of the companies who served the king by division, and the captains of thousands, and the captains of hundreds, and the rulers over all the substance and possessions of the king and of his sons, with the officers, and the mighty men, even all the mighty men of valor, to Jerusalem.
"I have chosen him to be my son, and I will be his father"  (1 Chronicles 28:6).  This and the following verse positively indicate that David was here basing what he said upon his understanding of the prophecy in 2S:7; however, that prophecy said nothing at all resembling what David here declared.  Solomon, in no sense whatever, was God's son, nor did God establish Solomon's throne for ... ever.  All that was happening in this chapter was taking place during David's lifetime, absolutely contrary to the specific declaration in  2 Samuel 7:12 that the promised Great One who would build that house for the name of God would do so, "When thou (David) shalt sleep with thy fathers, and that the Promised One would be SET UP AFTER THEE"  (2 Samuel 7:12).  Solomon was not set up after David but during David's reign; and God did not do it, as the prophecy indicated, but David did it!  (See our extensive comment on this in 2Samuel.)
