Therefore the redeemed of the Lord - This is probably the language of Yahweh assuring them, in answer to their prayer, that his ransomed people should again return to Zion.

And everlasting joy shall be upon their head - This entire verse occurs also in Isaiah 35:10. See it explained in the note on that verse. The custom of singing alluded to here on a journey is now very common in the East. It is practiced to relieve the tediousness of a journey over extended plains, as well as to induce the camels in a caravan to move with greater rapidity. The idea here is, that the caravan that should return from Babylon to Jerusalem, across the extended plains, should make the journey amidst general exultation and joy - cheered on their way by songs, and relieving the tedium of their journey by notes of gladness and of praise.

They shall obtain gladness and joy, and sorrow and mourning shall flee away - Nineteen MSS. and the two oldest editions have ישגו yasigu; and forty-six MSS. of Kennicott's and ten of De Rossi's, and the same two editions, and agreeably to them the Chaldee and Syriac, have ונסו venasu; and so both words are expressed, Isaiah 35:10, of which place this is a repetition. And from comparing both together it appears that the ו vau in this place is become by mistake in the present text final, nun of the preceding word.

Therefore the redeemed of the Lord shall return,.... Or "and", or "so" (q). In like manner, and as sure as the Israelites had a way made for them through the sea to pass over, so sure shall all those that are redeemed by the blood of Christ from sin, Satan, the law, death, and hell, be gathered out of the nations of the world, and from the antichristian states, and shall be converted and turn to the Lord. Or these words are a continuation of the above prayer, as Jarchi, "let them return"; or rather are an answer to it, and a promise that they should:

and come with singing unto Zion; to the Gospel church, and join themselves to it, praising God for his grace in calling and converting them, adoring the riches of his distinguishing love, and singing the new song of redeeming grace; and hereafter they shall return from the grave, and come to Zion above, singing the song of Moses and of the Lamb:

and everlasting joy shall be upon their head; visible in the present state, more so hereafter, when there will be upon them an eternal weight of glory, a crown of life and righteousness:

they shall obtain joy and gladness; by having the presence of God, communion with him, views of interest in Christ, and the gracious influences of the blessed Spirit; all these they enjoy in the church now, but in full perfection hereafter:

and sorrow and mourning shall flee away: either for sin, having the discoveries and application of forgiving love; or on account of desertion, now enjoying the light of God's countenance; or by reason of persecution, which in the latter day glory will entirely cease. But all this will be most fully accomplished in the New Jerusalem church state, and ultimate glory, Revelation 21:4. See Gill on Isaiah 35:10.

(q) "et nunc", V. L. "ita", Junius & Tremellius, Piscator. And Ben Melech observes, that "and", is in the room of "thus".

Therefore the redeemed of the LORD shall {l} return, and come with singing to Zion; and everlasting joy shall be upon their head: they shall obtain gladness and joy; sorrow and mourning shall flee away.

(l) From Babylon.

51:11 Therefore - This verse contains an answer to the prophet's prayer. I did these great things, and I will do the like again. Joy - Like a crown of glory.

11. (Isa 35:10).

Therefore-assurance of faith; or else the answer of Jehovah corresponding to their prayer. As surely as God redeemed Israel out of Egypt, He shall redeem them from Babylon, both the literal in the age following, and mystical in the last ages (Re 18:20, 21). There shall be a second exodus (Isa 11:11-16; 27:12, 13).

singing-image from the custom of singing on a journey when a caravan is passing along the extended plains in the East.

everlasting joy-(Jude 24).

sorrow . flee away-(Re 21:4).

51:9-16 The people whom Christ has redeemed with his blood, as well as by his power, will obtain joyful deliverance from every enemy. He that designs such joy for us at last, will he not work such deliverance in the mean time, as our cases require? In this world of changes, it is a short step from joy to sorrow, but in that world, sorrow shall never come in view. They prayed for the display of God's power; he answers them with consolations of his grace. Did we dread to sin against God, we should not fear the frowns of men. Happy is the man that fears God always. And Christ's church shall enjoy security by the power and providence of the Almighty.
