Jehovah guarding, etc. By strangers, orphans, and widows, the Psalmist means all those in general who are destitute of the help of man. While all show favor to those who are known to them and near to them, we know that strangers are, for the most part, exposed to injurious treatment. We find comparatively few who come forward to protect and redress widows and orphans; it seems lost labor, where there is no likelihood of compensation. Under these cases the Psalmist shows that whatever the grievance may be under which we suffer, the reason can only be with ourselves if God, who so kindly invites all who are in distress to come to him, does not stretch forth his arm for our help. On the other hand, he declares that everything will have an adverse and unfortunate issue to those who wickedly despise God. We have said upon the first Psalm, that by the way is meant the course of life in general. God will destroy the way of the wicked, inasmuch as he will curse all their counsels, acts, attempts, and enterprises, so that none of them shall have good success. However excellent they may be in planning, although they may be crafty and sharp-sighted, and abound in strength of resources of every kind, God will overturn all their expectations. While he extends his hand to those who are his people, and brings them through all obstacles, and even impassable ways, he on the contrary destroys the path of the wicked, when apparently most open and plain before them.

The Lord preserveth the strangers - He regards them with interest; he defends and guides them. This is the ninth reason why those who trust in the Lord are happy. The stranger - away from home and friends; with no one to feel an interest in him or sympathy for him; with the feeling that he is forsaken; with no one on whom he can call for sympathy in distress - may find in God one who will regard his condition; who will sympathize with him; who is able to protect and befriend him. Compare Exodus 12:49; Exodus 22:21; Exodus 23:9; Leviticus 19:33; Deuteronomy 1:16; Deuteronomy 10:18-19; Isaiah 56:3, Isaiah 56:6.
He relieveth the fatherless and widow - He is their friend. This is the tenth reason why those who put their trust in the Lord are happy. It is that God is the Friend of those who have no earthly protector. See the notes at Psalm 68:5 : "A father of the fatherless, and a judge of the widows, is God in his holy habitation."
But the way of the wicked he turneth upside down - He overturns their plans; defeats their schemes; makes their purposes accomplish what they did not intend they should accomplish. The Hebrew word here means to bend, to curve, to make crooked, to distort; then, to overturn, to turn upside down. The same word is applied to the conduct of the wicked, in Psalm 119:78 : "They dealt perversely with me." The idea here is, that their path is not a straight path; that God makes it a crooked way; that they are diverted from their design; that through them he accomplishes purposes which they did not intend; that he prevents their accomplishing their own designs; and that he will make their plans subservient to a higher and better purpose than their own. This is the eleventh reason why those who put their trust in God are happy. It is that God is worthy of confidence and love, because he has all the plans of wicked men entirely under his control.

Preserveth the strangers - He has preserved you strangers in a strange land, where you have been in captivity for seventy years; and though in an enemy's country, he has provided for the widows and orphans as amply as if he had been in the promised land.
The way of the wicked he turneth upside down - He subverts, turns aside. They shall not do all the wickedness they wish; they shall not do all that is in their power. In their career he will either stop them, turn them aside, or overturn them.

The LORD preserveth the (g) strangers; he relieveth the fatherless and widow: but the way of the wicked he turneth upside down.
(g) Meaning, all who are destitute of worldly means and help.

The Lord preserveth the strangers,.... The life of them, as he did the daughter of: the Greek, a Syrophenician woman, and a Samaritan, by healing them of their diseases, Mark 7:26; and in a spiritual sense he preserves the lives and saves the souls of his people among the Gentiles, who are aliens from the commonwealth of Israel, and strangers to the covenant of promise; for these he laid down his life a ransom, and became the propitiation for their sins; to these he sends his Gospel, which is the power of God to salvation unto them;
he relieveth the fatherless and widow; in their distresses and troubles, who have no helper; a wonderful instance of his relieving a widow, in the most disconsolate circumstances, we have in raising the widow of Nain's son to life, and restoring him to his mother, Luke 7:12; in him "the fatherless", and all that in a spiritual sense are destitute of help in the creatures, and see they are so, "find mercy"; nor will he leave his people comfortless, or as orphans and fatherless ones, but will and does come and visit them, relieve and supply them with everything convenient for them; though his church here on earth may seem to be as a widow, he being in heaven at the right hand of God, yet he cares for her in the wilderness, and provides for her support, where she is nourished with the word and ordinances, and will be until he comes again; see Hosea 14:3;
but the way of the wicked he turneth upside down; so that they cannot find it; nor their hands perform their enterprise; their schemes and counsels are all confounded and blasted by him, and all their policy and power are not able to prevail against his church and people; see Psalm 1:6.
