Parallel
Genesis 6:3
Brenton's English Septuagint · Berean Standard Bible
And the Lord God said, My Spirit shall certainly not remain among these men for ever, because they are flesh, but their days shall be an hundred and twenty years.
So the LORD said, “My Spirit will not contend with man forever (note: LXX and Syriac My Spirit will not remain in man forever), for he is mortal; his days shall be 120 years.”
