This will happen because they left God. They prayed to Ashtoreth, Chemosh, and Milcom. They did not walk in God’s way or keep God’s rules like David did. ♂️❌
For they have forsaken Me to worship Ashtoreth the goddess of the Sidonians, Chemosh the god of the Moabites, and Milcom the god of the Ammonites. They have not walked in My ways, nor done what is right in My eyes, nor kept My statutes and judgments, as Solomon’s father David did.
KJV
Because that they have forsaken me, and have worshipped Ashtoreth the goddess of the Zidonians, Chemosh the god of the Moabites, and Milcom the god of the children of Ammon, and have not walked in my ways, to do [that which is] right in mine eyes, and [to keep] my statutes and my judgments, as [did] David his father.
