Psalms 18:26

With the pure - Those who are pure in their thoughts, their motives, their conduct.

Thou wilt show thyself pure - They will find that they have to deal with a God who is himself pure; who loves purity, and who will accompany it with appropriate rewards wherever it is found.

And with the froward - The word used here - עקשׁ ‛iqqêsh - means properly perverse; a man of a perverse and wicked mind. It is derived from a verb - עקשׁ ‛âqash - which means, to turn the wrong way, to wrest, to pervert. It would be applicable to a man who perverts or wrests the words of others from their true meaning; who prevaricates or is deceitful in his own conduct; who is not straightforward in his dealings; who takes advantage of circumstances to impose on others, and to promote his own ends; who is sour, harsh, crabbed, unaccommodating, unyielding, unkind. It is rendered perverse in Deuteronomy 32:5; Proverbs 8:8; Proverbs 19:1; Proverbs 28:6; froward here, and in 2 Samuel 22:27; Psalms 101:4; Proverbs 11:20; Proverbs 17:20; Proverbs 22:5; and crooked in Proverbs 2:15. The word does not occur elsewhere in the Old Testament.

Thou wilt show thyself froward - Margin, wrestle. In the corresponding place in 2 Samuel 22:27 it is rendered, “Thou wilt show thyself unsavory;” though the same word is used in the original. In the margin in that place, as here, the word is wrestle. The original word in each place - פתל pâthal - means to twist, to twine, to spin; and then, to be twisted; to be crooked, crafty, deceitful. In the form of the word which occurs here (Hithpael), it means, to show oneself crooked, crafty, perverse. (Gesenius, Lexicon). It cannot mean here that God would assume such a character, or that he would be crooked, crafty, perverse in his dealings with men, for no one can suppose that the psalmist meant to ascribe such a character to God; but the meaning plainly is, that God would deal with the man referred to according to his real character: instead of finding that God would deal with them as if they were pure, and righteous, and merciful, such men would find that he deals with them as they are - as perverse, crooked, wicked.
