Unto God, that performeth all things for me— To the Divinity that completely covereth me all over: literally, that perfecteth all over, or around me: "That completely shelters me all around, namely, under his wing:" Mudge: and compare Psalms 138:8. Dr. Chandler observes, that the word גמר gomeir rendered performeth, signifies to perfect and consummate, or to do every thing necessary for a person in his particular station and character. Thus in the Syriac version of the New Testament the word is used of Christ's being made perfect by sufferings; Hebrews 12:2 and this rendering well suits the place before us. "It is God who effectually doth every thing concerning me: that is, which is necessary to my safety."
