Then, namely, when a person acts in accordance with the suggestion made in the first part of the chapter, shall thy light break forth as the morning, like the dawn of the Orient, which speedily covers the sky, and thine health shall spring forth speedily, the spiritual healing going on with great rapidity; and thy righteousness, the deliverance promised in the covenant, shall go before thee, as the pillar of Jehovah did at the time of the wilderness journey; the glory of the Lord shall be thy rearward, to protect him against any attack from that quarter. This is nothing else than the glory of God in the face of Jesus Christ, the Messiah Himself. Cf 2 Corinthians 4:6; 1 Corinthians 10:4.
