2 Kings 8:18
And he walked in the way of the kings of Israel, as did the house of Ahab: for the daughter of Ahab was his wife: and he did evil in the sight of the LORD.
And he walked in the way of the king's of Israel, as did the house of Ahab,.... Imitated them in idolatry:
for the daughter of Ahab was his wife; whose name was Athaliah, 2 Kings 8:26, and by her he was drawn into idolatrous practices; of such bad consequence are marriages with idolaters; it is very much that so good a king as Jehoshaphat his father was should contract such an affinity; he suffered for it in more instances than one:
and he did evil in the sight of the LORD; was guilty of idolatry, than which nothing was more displeasing to the Lord; for he made high places, and compelled his subjects to commit idolatry, 2 Chronicles 21:11.
