Psalms 55:20 - Exposition

He hath put forth his hands against such as be at peace with him. Some explain "he" as "the wicked collectively,'' and maintain that in this verse and the next no particular person is pointed at; but it seems better to regard the psalmist as "suddenly reverting to the fixed and deepest thought in his heart—the treachery of his friend" (Canon Cook). Ahithophel had put forth his hand against such as were at peace with him." He hath broken his covenant . The covenant of friendship with David ( Psalms 55:14 ), not, perhaps, a formal one, but involved in the terms on which they stood one towards the other.
