And He said, Your name will no longer be called Jacob, but Israel; for you have struggled with God and with men, and have prevailed.
2 Corinthians 3:18
But we all with unveiled face, beholding and reflecting like a mirror the glory of the Lord, are being transformed into the same image from glory to glory, even as from the Lord Spirit.
