2 Chronicles 17:10

Ramb. has already so understood the connection of these verses (erat hoc praemium pietatis Josaphati, quod vicini satisque potentes hostes non auderent adversus ipsum hiscere); while Berth. fails to apprehend it, saying that Jehoshaphat had time to care for the instruction of his people, because at that time the neighbouring peoples did not venture to undertake war against Judah.
