Therefore my people shall know my name - The idea in this verse is, that his people should have such exhibitions of his power as to furnish to them demonstration that he was God.

Therefore my people shall know - The word לכן lachen, occurring the second time in this verse, seems to be repeated by mistake. It has no force nor emphasis as a repetition; it only embarrasses the construction and the sense. It was not in the copies from which the Septuagint, Syriac, and Vulgate were translated; it was not in the copy of the Septuagint from which the Arabic was translated; but in the Aldine and Complutensian editions δια τουτο is repeated; probably so corrected, in order to make it conformable with the Hebrew text.

I am he that Moth speak "I am he, Jehovah, that promised" - For הוא hu, the Bodleian MS. and another have יהוה, Jehovah; "For I am Jehovah that promised;" and another ancient MS. adds יהוה Jehovah after הוא hu. The addition of Jehovah seems to be right in consequence of what was said in the preceding line, "My people shall know my name."

Therefore my people shall know my name,.... His nature and perfections; his faithfulness in fulfilling his promises to them; his power in delivering them out of their bondage; and his justice in punishing their enemies.

Therefore they shall know on that day that I am he that doth speak: behold, it is I; they shall then see, when the people of God are delivered from the antichristian slavery and bondage, and when Babylon is fallen, that all the promises God has spoken are yea and amen; that Jesus Christ is the true and faithful witness; and that these are his true and faithful sayings, which he has spoken.

Therefore my people shall know my name: therefore they shall know in that day that I am he that doth speak: behold, it is I.

52:6 Shall know - They shall experience my power and goodness in fighting for them. In that day - When I shall redeem my people: which work was begun by the return of the Jews from Babylon, and perfected by the coming of the Messiah. Behold - That all these promises are the words of the omnipotent, unchangeable God.

6. shall know in that day-when Christ shall reveal Himself to Israel sensibly; the only means whereby their obstinate unbelief shall be overcome (Ps 102:16; Zec 12:10; 14:5).

52:1-12 The gospel proclaims liberty to those bound with fears. Let those weary and heavy laden under the burden of sin, find relief in Christ, shake themselves from the dust of their doubts and fears, and loose themselves from those bands. The price paid by the Redeemer for our salvation, was not silver or gold, or corruptible things, but his own precious blood. Considering the freeness of this salvation, and how hurtful to temporal comfort sins are, we shall more value the redemption which is in Christ. Do we seek victory over every sin, recollecting that the glory of God requires holiness in every follower of Christ? The good news is, that the Lord Jesus reigns. Christ himself brought these tidings first. His ministers proclaim these good tidings: keeping themselves clean from the pollutions of the world, they are beautiful to those to whom they are sent. Zion's watchmen could scarcely discern any thing of God's favour through the dark cloud of their afflictions; but now the cloud is scattered, they shall plainly see the performance. Zion's waste places shall then rejoice; all the world will have the benefit. This is applied to our salvation by Christ. Babylon is no place for Israelites. And it is a call to all in the bondage of sin and Satan, to use the liberty Christ has proclaimed. They were to go with diligent haste, not to lose time nor linger; but they were not to go with distrustful haste. Those in the way of duty, are under God's special protection; and he that believes this, will not hasten for fear.
