“Noah was a righteous man, blameless in his time…”
This is also echoed in 7:1 – “…for you alone I have seen to be righteous before me in this time“. Does this merely mean that Noah was righteous compared to those in his generation, but possibly not altogether righteous? Was Noah just “good enough”? With the included statement “in his time”, not once, but in both 6:9 and 7:1, we may be tempted to assume that Noah was just above average. But, it also says in verse 9 that he walked with God. Also, Friedman’s commentary points out that the Hebrew word used for blameless is the same word used in other places referring to sacrificial animals, and argues that as a sacrifice must be spotless or unblemished, this leaves no room for imperfection. So it is probably safe to say that Noah was not merely righteous compared to an otherwise wicked generation, but he would have been considered righteous in any generation.
