What does 1 Kings 11:38 mean?

and if you listen to what I say, live the way I want, and do what’s right—just like my servant David did—then I’ll be with you. I’ll build you a lasting dynasty, just like I did for David, and I’ll give Israel to you. 1 Kings 11:38 - Modern Text Bible

(God offers Jeroboam the same kind of promise he gave David: if Jeroboam is faithful, his family will rule for generations.)
