In this section David asked God to deliver him from enemies who were trying to kill him without cause.
35:1-3 David appealed to the Lord for defense as to a champion who goes out in battle for another (cf. Josh. 5:13-15).
35:4-6 He asked God to rout his enemies and to humiliate them. He wished God would blow them away as chaff and take away their stability so they would fall. The Angel of the Lord is the leader of God's heavenly army, the preincarnate Christ (cf. 34:7). David wanted Him to do to his enemies what they intended to do to him. This is in keeping with how God usually deals with the wicked.
35:7-8 The reason for David's request was his enemys' unwarranted attempts to kill him. He prayed they might experience the fate they hoped would be his.
35:9-10 If God granted deliverance, David promised to rejoice in the Lord and to praise Him.
"My soul(9) and my bones(10) are two emphatic ways of saying I' or myself,' as in 6:2, 3; cf. our own expression I know it in my bones'."89
