It appears, that in the days of David, Moab was under tribute to Israel, and paid gifts 2 Samuel 8:2. And it should seem, that Moab had at the time of the Prophet's ministry, withdrawn her allegiance. Hence the Prophet admonisheth Moab to revive this payment. And as in the days of Mesha, king of Moab, this tribute was paid in lambs, the Prophet recommends Moab to do so now; 2 Kings 3:4, But is there not a spiritual lesson, of a much higher nature, intended by the Prophet's direction to Moab? Israel was about to go into captivity, and Moab was under the heavy displeasure of the Lord: Now, said the prophet to Moab, offer up the lamb for an offering in sacrifice, with an eye to Christ. Seek pardon and peace through his blood; and in token of your sense of sin before God, be kind and affectionate to the Lord's people; hide the outcasts of the Lord's heritage, and look unto mount Zion: otherwise, Moab will be utterly spoiled, and scattered, and driven away, as a wandering bird.
