Isaiah 52:10

Jehovah has wrought out salvation through judgment in the sight of all the world. "Jehovah hath made bare His holy arm before the eyes of all nations, and all the ends of the earth see the salvation of our God." As a warrior is accustomed to make bare his right arm up to the shoulder, that he may fight without encumbrance (exsertare humeros nudamque lacessere pugnan, as Statius says in Theb. i. 413), so has Jehovah made bare His holy arm, that arm in which holiness dwells, which shines with holiness, and which acts in holiness, that arm which has been hitherto concealed and therefore has appeared to be powerless, and that in the sight of the whole world of nations; so that all the ends of the earth come to see the reality of the work, which this arm has already accomplished by showing itself in its unveiled glory - in other words, "the salvation of our God."

The greater part of this chapter is on the same subject with the chapter before, concerning the deliverance of the Jews out of Babylon, which yet is applicable to the great salvation Christ has wrought out for us; but the last three verses are on the same subject with the following chapter, concerning the person of the Redeemer, his humiliation and exaltation. Observe, I. The encouragement that is given to the Jews in captivity to hope that God would deliver them in his own way and time (Isa 52:1-6). II. The great joy and rejoicing that shall be both with ministers and people upon that occasion (Isa 52:7-10). III. The call given to those that remained in captivity to shift for their own enlargement when liberty was proclaimed (Isa 52:11, Isa 52:12). IV. A short idea given here of the Messiah, which is enlarged upon in the next chapter (Isa 52:13-15).

52:10 victory of our God: The rescue of God’s people from disgrace foreshadows an even greater victory when God will reign victoriously to the ends of the earth (note the many similarities with Ps 98:1-3).
