Here in the passage, the Lord is promising of a garment of salvation and the robe of righteousness. In Milon's "Paradise Lost", Milton mentions that our early parents Adam and Eve were adorned with glorious garments. There was no instance for shame as long as they were arrayed with the attire of God's glory. However, as soon as they disobeyed and sinned, they lost the glorious charm and found themselves shameful and naked. In spite of their fall, the God clothed with animal hides. He did not want them to roam naked and be ashamed.
