... Noah was a righteous man, the only blameless person living on earth at the time ... (NLT)
... Noah was a righteous man, blameless among the people of his time ... (NIV)
... Noah was a righteous man, blameless in his generation. ... (ESV)
... Noah was a just man, perfect in his generations. ... (NKJV)
There's quite a bit of variety in how this (part of the) verse is translated. Is the NLT's translation that Noah was the only blameless person within the range of what the Hebrew could mean?
