The Covenant of the Redeemer

Isaiah 59:20-21

And a Redeemer will come to Zion, and unto them that turn from transgression in Jacob, saith Jehovah.

And as for me, this is my covenant with them, saith Jehovah: my Spirit that is upon thee, and my words which 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 Jehovah, from henceforth and for ever.
