3. He assures them of the mercy God had in store for his people. (1.) That they should not long need their kindness, or be troublesome to them: For the extortioner is almost at an end already, and the spoiler ceases. God's people shall not be long outcasts; they shall have tribulation ten days (Rev. ii. 10), and that is all. The spoiler would never cease spoiling if he might have his will; but God has him in a chain. Hitherto he shall go, but no further. (2.) That they should, ere long, be in a capacity to return their kindness (v. 5): "Though the throne of the ten tribes be sunk and overturned, yet the throne of David shall be established in mercy, by the mercy they receive from God and the mercy they show to others; and by the same methods may your throne be established if you please." It would engage great men to be kind to the people of God if they would but observe, as they easily might, how often such conduct brings the blessing of God upon kingdoms and families. "Make Hezekiah your friend, for you will find it your interest to do so upon the account both of the grace of God in him and the presence of God with him. He shall sit upon the throne in truth, and then he does indeed sit in honour and sit firmly. Then he shall sit judging, and will then be a protector to those that have been a shelter to the people of God." And see in him the character of a good magistrate. [1.] He shall seek judgment; that is, he shall seek occasions of doing right to those that are wronged, and shall punish the injurious even before they are complained of: or he shall diligently search into every cause brought before him, that he may find where the right lies. [2.] He shall hasten righteousness, and not delay to do justice, nor keep those long waiting that make application to him for the redress of their grievances. Though he seeks judgment, and deliberates upon it, yet he does not, under pretence of deliberation, stay the progress of the streams of justice. Let the Moabites take example by this, and then assure themselves that their state shall be established.
