1 Kings 11:37

And I will take thee, and thou shalt reign according to all that thy soul desireth, and shalt be king over Israel.

The verse foretold Jeroboam's elevation to the throne of Israel. The prediction was given through Ahijah many years before Jeroboam reigned. Its fulfillment began when Jeroboam became king. During his reign apostasy increased and set the kingdom on a course toward eventual downfall and ruin. That same apostasy also brought ruin upon his own house.
