Isaiah 35:6

Then shall the lame man, who by reason of his self-righteousness was unable to walk the way of God's commandments, leap as an hart, in eager willingness to do the Lord's bidding, and the tongue of the dumb, of him who formerly knew nothing of the Gospel and therefore confessed nothing, sing, in hymns of thanksgiving to the God of his salvation; for in the wilderness shall waters break out and streams in the desert, for the grace and mercy of God in the New Testament era flows in rich streams to those who thirst for His forgiveness. Cf Psalms 65:9.
