"Therefore, O Lord, God of Israel, keep for your servant, my father David, that which you promised him, saying, 'There shall never fail you a successor before me to sit on the throne of Israel, if only your children keep to their way, to walk in my law as you have walked before me.' Therefore, O Lord, God of Israel, let your word be confirmed, which you promised to your servant David." (2 Chronicles 6:16-17, NRSV)
Therefore, O Lord God of Israel, keep with thy servant David my father that which thou hast promised him, saying, There shall not fail thee a man in my sight to sit upon the throne of Israel; yet so that thy children take heed to their way to walk in my law, as thou hast walked before me. Now then, O Lord God of Israel, let thy word be verified, which thou hast spoken unto thy servant David. (2 Chronicles 6:16-17, KJV)
Solomon reminds God of his promise about a Davidic dynasty, but he knows that this promise is conditional on the people remaining faithful to the commandments. It's common in the Bible for people to remind God about various agreements he made, even to quote his own words back to him. Solomon's statement is part of a pretty dramatic moment: God had just descended into the Temple in a cloud and Solomon addresses him in front of the entire congregation of Israel. In this case, the reminder of the promise seems for the benefit of the people. Solomon's saying that if they want him and the rest of David's descendants to be blessed, they'd better follow the laws. Plus, Solomon is publicly affirming that, as David's son, he's the legitimate ruler. Just in case anyone forgot.
Quote #2
As for you, if you walk before me, as your father David walked, doing according to all that I have commanded you and keeping my statutes and my ordinances, then I will establish your royal throne, as I made covenant with your father David saying, "You shall never lack a successor to rule over Israel." (2 Chronicles 7:17-18, NRSV)
As for thee, if thou wilt walk before me, as David thy father walked, and do according to all that I have commanded thee, and shalt observe my statutes and my judgments; Then will I establish the throne of thy kingdom, according as I have covenanted with David thy father, saying, There shall not fail thee a man to be ruler in Israel. (2 Chronicles 7:17-18, KJV)
God comes right back at Solomon. He promises to keep the throne in the family—one of David's descendants will always be in charge in Israel. But is God prepared to stick with the family no matter how bad things get with these guys? It doesn't seem so. God makes it clear that Solomon needs to emulate his father and observe God's rules if he wants to establish the dynasty. Is God's assumption that any descendant of David is guaranteed to be faithful? Spoiler alert: DNA doesn't guarantee anything.
Quote #3
[Israel] answered the king, "What share do we have in David? We have no inheritance in the son of Jesse. Each of you to your tents, O Israel! Look now to your own house, O David." […] So Israel has been in rebellion against the house of David to this day. (2 Chronicles 10:16, 19, NRSV)
[Israel] answered the king, saying, What portion have we in David? and we have none inheritance in the son of Jesse: every man to your tents, O Israel: and Now David, see to thine own house […] And Israel rebelled against the house of David unto this day. (2 Chronicles 10:16, 19, KJV)
The 10 northern tribes feel free to rebel because they don't feel like they have any kinship ties with David and his tribe of Judah. They realize that as long as they stay in the unified kingdom, they'll never have one of their own on the throne.
