Charles H. Spurgeon on Psalms 146:9

The Lord preserveth the strangers. Many monarchs hunted aliens down, or transported them from place to place, or left them as outlaws unworthy of the rights of man; but Jehovah made special laws for their shelter within his domain. In this country the stranger was, a little while ago, looked upon as a vagabond, —a kind of wild beast to be avoided if not to be assaulted; and even to this day there are prejudices against foreigners which are contrary to our holy religion. Our God and King is never strange to any of his creatures, and if any are left in a solitary and forlorn condition he has a special eye to their preservation. He relieveth the fatherless and widow. These excite his compassion, and he shows it in a practical way by upraising them from their forlorn condition. The Mosaic law made provision for these destitute persons. When the secondary fatherhood is gone the child falls back upon the primary fatherhood of the Creator; when the husband of earth is removed the godly widow casts herself upon the care of her Maker. But the way of the wicked he turneth upside down. He fills it with crooked places; he reverses it, sets it down, or upsets it. That which the man aimed at he misses, and he secures that for himself which he would gladly have avoided. The wicked man's way is in itself a turning of things upside down morally, and the Lord makes it so to him providentially: everything goes wrong with him who goes wrong.
