These are beautiful verses, and full of gospel. The Lord recommends Moab to give shelter to Israel. They are outcasts, but still they are the Lord's. Is this Zion (said the nations, in Jerusalem's mourning) is this Zion, whom men call the perfection of beauty, the joy of the whole earth? Lamentations 2:15. Now Moab is advised to take the Lord's outcasts in, and give them welcome in the day of their calamity. And the motives for doing so are added: In mercy shall the throne be established: that is, Jesus, the seed of David, will erect his throne in mercy, and the Gentiles, as well as the Jews, shall partake of the blessings which will issue from his throne. Therefore seek the favor of this almighty King, by being kind to the King's people. Reader! the same advice holds good in all ages, and among all nations. And who shall say, if the Lord inclines the heart of sinners to be kind to the Lord's distressed saints, might it not encourage an hope, that he who gives the grace of love to his people, will give the grace of faith and repentance towards himself?
