The Covenant of the Redeemer

Isaiah 59:20-21

And there shall come a redeemer to Sion, and to them that return from iniquity in Jacob, saith the Lord.

This is my covenant with them, saith the Lord: My spirit that is in thee, and my words that I have put in thy mouth, shall not depart out of thy mouth, nor out of the mouth of thy seed, nor out of the mouth of thy seed's seed, saith the Lord, from henceforth and for ever.
