From heaven, as it is explained in the next clause, which is the Lord's sanctuary, or holy place, where he dwells, even in the height of it; it is both high and holy, as he himself is; yet he condescends to look down from thence on sinful mortals: from heaven did the Lord behold the earth; the inhabitants of it, good and bad: it designs the general notice he takes of men and things in a providential way; he beholds the world, that lies in wickedness, and all the wickedness committed in it; and will one day call to an account, and punish for it; he beholds good men, not only with an eye of providence, to take care of them, protect and defend, but with an eye of love, grace, and mercy; he has a special and distinct knowledge of them, and it may here particularly regard the notice he takes of his people, under antichristian tyranny; he sees all the barbarity and cruelty exercised upon them, and will requite it, ere long, to their adversaries, and free them from it, as follows.
