1 Kings 14:11-20
As for you, go back home. When you set foot in your city, the boy will die. All Israel will mourn for him and bury him. He is the only one belonging to Jeroboam who will be buried, because he is the only in the house of Jeroboam in whom the Lord, the God of Israel, has found anything good.
The Lord will raise up for himself a king over Israel who will cut off the family of Jeroboam.
Because they provoke the Lord to anger by making Asherah poles. And he will give Israel up because of the sins Jeroboam has committed and has caused Israel to commit.
It is meaning that all the rest of house of Jeroboam will die violently.
Scatter them beyond the Euphrates: Israel was taken into exile by Assyria after the fall of Samaria.
Why?
Jerobaom solved his son's ill he thought the prophet Ahijah, but he keep gripping the control power to Israel. So he won't turn back to the Lord. His heart has been obscured by his greed.
How?
Don't be a christian worship the Lord and the world, when there is emergence event happened then come the Lord.  The Lord knows our heart. So let show the royalty to the Lord.
