20:35 After this - This is mentioned as an aggravation of his sin, after so great an obligation laid upon him by God; and after he had been so singularly reproved by a prophet yet he relapsed into the same sin which proceeded partly from that near relation which was contracted between the two families, and partly from the easiness of Jehoshaphat's temper, which could not resist the solicitations of others, in such things as might seem indifferent. For he did not join with him in war, as he did with Ahab, but in a peaceable way only, in a matter of trade and commerce. And yet God reproves and punisheth him for it, ver.37, to shew his great dislike of all familiar conversation of his servants and people with professed enemies of God and of religion, as Ahaziah was. Very wickedly - Or who did industriously, and maliciously, and constantly work wickedness, as the Hebrew phrase implies, giving himself up to idolatry and all wickedness.
20:31-37 Jehoshaphat kept close to the worship of God, and did what he could to keep his people close to it. But after God had done such great things for him, given him not only victory, but wealth; after this, to go and join himself with a wicked king, was very ungrateful. What could he expect but that God would be angry with him? Yet it seems, he took the warning; for when Ahaziah afterward pressed him to join him, he would not, 1Ki 22:49. Thus the alliance was broken, and the Divine rebuke had its effect, at least for a season. Let us be thankful for any losses which may have prevented the loss of our immortal souls. Let us praise the Lord, who sought after us, and left us not to perish in our sins.
