Isaiah 35:10 - Matthew Poole's English Annotations on the Holy Bible

The ransomed of the Lord; they whom God shall rescue and redeem from their corporal slavery in Babylon, and especially from their spiritual bondage under sin and Satan. Shall return, and come to Zion; shall come again to Zion, from whence they had been carried away captive. Or, shall return, to wit, to the Lord now mentioned, and come to Zion, i.e. join themselves to God's church and people. Sorrow and sighing shall flee away; which expressions are too magnificent and emphatical to be satisfied by the return of the Jews from Babylon to their own land, which was accompanied and followed with many sighs and sorrows, as appears, both from sacred and other historians; and therefore must necessarily be understood of gospel times, and of the joy and happiness purchased by Christ for his people, begun here, and continued to all eternity.
