1 Kings 9:4-5

4You must continue to serve me honestly and obey me, as your father David did. Do everything that I have commanded you to do. Obey my rules and my laws.

5If you serve me truly, I will cause one of your descendants to rule over Israel as king for all time. That is what I promised to your father David when I said, “There will always be someone from your family to rule Israel as king.”
