This is a perfect example for all to see how the MT leads one to understand the faith differently.
The Septuagint (LXX) says:
"For I know that he is eternal ( aenaoV ) who is about to deliver me, and to raise up upon the earth my skin that endures these sufferings: for these things have been accomplished to me of the Lord; which I am conscious of in myself, which mine eye has seen, and not another, but all have been fulfilled to me in my bosom."
No mention of the "latter day" either my friend. The Eternal one is about to lift his sufferings now. We are not using the same Bible. I have said that many times before.
The Hebrew word used definitely means a redeemer.
