King James Version
3And the LORD said, My spirit shall not always strive with man, for that he also is flesh: yet his days shall be an hundred and twenty years.
Young’s Literal Translation
3And Jehovah saith, `My Spirit doth not strive in man – to the age; in their erring they [are] flesh:’ and his days have been an hundred and twenty years.
Two very different translations. Which is it and what does it mean?
