The Lord was with Jehoshaphat because he followed the example of his father David’s earlier days and did not seek the Baals,

For the sons of the wicked Athaliah had broken into the house of God and even used the holy things of the house of the Lord for the Baals.

But he walked in the ways of the kings of Israel; he also made molten images for the Baals.

For he rebuilt the high places which Hezekiah his father had broken down; he also erected altars for the Baals and made Asherim, and worshiped all the host of heaven and served them.

They tore down the altars of the Baals in his presence, and the incense altars that were high above them he chopped down; also the Asherim, the carved images and the molten images he broke in pieces and ground to powder and scattered it on the graves of those who had sacrificed to them.
