2. The answer which is to be given to the messengers of the nations is, (1.) That God is and will be a faithful friend to his church and people, and will secure and advance their interests. Tell them that the Lord has founded Zion. This gives an account both of the work itself that is done and of the reason of it. What is God doing in the world, and what is he designing in all the revolutions of states and kingdoms, in the ruin of some nations and the rise of others? He is, in all this, founding Zion; he is aiming at the advancement of his church's interests; and what he aims at he will accomplish. The messengers of the nations, when they sent to enquire concerning Hezekiah's successes against the Philistines, expected to learn by what politics, counsels, and arts of war he carried his point; but they are told that these successes were not owing to any thing of that nature, but to the care God took of his church and the interest he had in it. The Lord has founded Zion, and therefore the Philistines must fall. (2.) That his church has and will have a dependence upon him: The poor of his people shall trust in it, his poor people who have lately been brought very low, even the poorest of them; they more than others, for they have nothing else to trust to, Zeph. iii. 12, 13. The poor receive the gospel, Matt. xi. 5. They shall trust to this, to this great truth, that the Lord has founded Zion; on this they shall build their hopes, and not on an arm of flesh. This ought to give us abundant satisfaction as to public affairs, that however it may go with particular persons, parties, and interests, the church, having God himself for its founder and Christ the rock for its foundation, cannot but stand firm. The poor of his people shall betake themselves to it (so some read it), shall join themselves to his church and embark in its interests; they shall concur with God in his designs to establish his people, and shall wind up all on the same plan, and make all their little concerns and projects bend to that. Those that take God's people for their people must be willing to take their lot with them and cast in their lot among them. Let the messengers of the nations know that the poor Israelites, who trust in God, having, like Zion, their foundation in the holy mountains (Ps. lxxxvii. 1), are like Zion, which cannot be removed, but abides for ever (Ps. cxxv. 1), and therefore they will not fear what man can do unto them.
