Komentarz do Diwrej ha-jamim II 20:32

And he went in the way of his father Asa and did not turn away From what did he not turn away? to do what was right From the good and upright way of his father he did not turn away, but from the bad ways of Asa he did turn away, as is written (above 16:2): “And Asa brought forth silver and gold,” and the entire incident, but Jehoshaphat did not do so, but trusted in the Holy One, blessed be He, all his life.
