Isaiah 52:10

Here (if not already in Isaiah 52:9) the prophet withdraws his gaze from the future, and describes Jehovah as preparing Himself for the conflict which leads to the joyous scene of Isaiah 52:7 f.

hath made bare his holy arm throwing back the sleeveless upper garment from the right shoulder, in readiness for action: δεξιὸν ὦμον γυμνὸν ἔχων ἐν τῇ μάχῃ (Arrian, Alex.5. 18, quoted by Dillmann). See the contrasted metaphor in Psalms 74:11. his holy armmeans "His divine arm" (Psalms 98:1). The "arm" of Jehovah, as ch. Isaiah 51:9 (cf. also Isaiah 53:1).

shall see the salvation(i.e. the deliverance or "victory") of our God a different idea from that of Isaiah 45:22.
