Verses 26-28. -

"With the pious man thou wilt show thyself pious;
With the perfect man thou wilt show thyself perfect;
With the pure thou wilt show thyself pure;
And with the crooked thou wilt show thyself perverse.
And the afflicted people thou wilt save;
And thine eyes are upon the haughty, to bring them down." Having affirmed his integrity, and that God therefore had pleasure in him and rewarded him, David now asserts that this is the unfailing rule of God's dealings with men. The general current of their lives is so ordered as to be in harmony with their characters. It is not by luck or good fortune that prosperity attends the righteous, nor is it by chance that things go awry with the fraudulent, but it is by the law of God's providence. Pious. The Hebrew word means "pious" in the original sense of the word, which includes kindness to men as well as love to God. Perverse. In the Authorized Version "unsavoury." Really it is the same word as that used in Psalm 18:26, and signifies "thou wilt make thyself twisted," only the form is archaic, as is the case with some other words here. Experience confirms the psalmist's verdict. For constantly a strange perversity of fortune and an untowardness of events are the lot of those whose hearts are crooked. Afflicted. The word in the original includes the idea of humility, and so leads naturally on to the thought of the abasement of the proud. In the psalm the somewhat harsh expression used here has been softened into the more easy phrase, "The haughty eyes thou wilt bring down."

22:1-51 David's psalm of thanksgiving. - This chapter is a psalm of praise; we find it afterwards nearly as Ps 18. They that trust God in the way of duty, shall find him a present help in their greatest dangers: David did so. Remarkable preservations should be particularly mentioned in our praises. We shall never be delivered from all enemies till we get to heaven. God will preserve all his people, 2Ti 4:18. Those who receive signal mercies from God, ought to give him the glory. In the day that God delivered David, he sang this song. While the mercy is fresh, and we are most affected with it, let the thank-offering be brought, to be kindled with the fire of that affection. All his joys and hopes close, as all our hopes should do, in the great Redeemer.With the merciful thou wilt show thyself merciful, and with the upright man thou wilt show thyself upright. See Gill on Psalm 18:25.
