He, i.e. they, the persons last mentioned. Before the singular number, Psalms 55:13,14, was suddenly changed into the plural, Psalms 55:15, that the punishment might reach not him only, but his partners, in those treacherous and treasonable actions; and here is as sudden a change from the plural into the singular, and he returns to that person who was the chief contriver and promoter of this rebellion under Absalom, even to Ahithophel, of whom he spoke Psalms 55:13; and though he doth not excuse the rest, as we have seen, yet he lays the chief blame upon him, and here he adds new aggravations of his treason. Hath put forth his hands, in way of force or violence, as this phrase is used, Genesis 37:22 1 Samuel 26:9 Nehemiah 13:21 Acts 12:1. Against such as be at peace with him; against me, who gave him no provocation nor disturbance, but lived in great peace, and security, and friendship with him. Hath broken his covenant; all those solemn obligations by which he was tied to me, both as his king and as his friend.
