The right hand of the LORD is exalted: the right hand of the LORD does valiantly.
Read Chapter 118
Augustine of Hippo
AD 430
10. "The right hand of the Lord hath brought mighty things to pass" (ver. 16). What mighty things? saith he. "The right hand of the Lord," he saith, "hath exalted me." It is a mighty thing to exalt the humble, to deify the mortal, to bring perfection out of infirmity, glory from subjection, victory from suffering, to give help, to raise from trouble; that the true salvation of God might be laid open to the afflicted, and the salvation of men might remain of no avail to the persecutors. These are great things: but what art thou surprised at hear what he repeateth: "The right hand of the Lord hath brought mighty things to pass."
Me is not in Hebrew. All salvation is from God. (Berthier)
Right hand, repeated thrice, insinuates the blessed Trinity, as the word Lord is applied to Christ, who effected man's redemption with singular efficacy. (Worthington)
