Though I walk in the midst of trouble, thou wilt revive me (comp. Psalms 23:4). David "walked in the midst of trouble" during the greater part of his life. When the persecution of Saul was over, he had trouble from foreign enemies (2 Samuel 5-12.
); when these were subdued, his domestic troubles began (2 Samuel 13-19.; 1 Kings 5:1-18 :53). God, however, from time to time "gave him a reviving." Thou shalt stretch forth thine hand against the wrath of mine enemies (comp.
Psalms 3:7; Psalms 9:3-6; Psalms 18:14-17, etc.). What God had so often done for him, David is confident that he will do again. He will break the power of his enemies, and deliver him from their machinations.
And thy right hand. The symbol of strength. Shall save me; or, "deliver me" (comp. Psalms 18:35; Psalms 60:5; Psalms 63:8; Psalms 108:6, etc.).
