According to biblical accounts, Lamech did express doubt about Noah’s lineage, particularly in his naming of Noah, which means "rest" or "comfort," suggesting he hoped Noah would bring relief from the curse on the ground. Some interpretations suggest that Noah did not physically resemble Lamech or his kin, as Noah was described as "righteous" and "blameless" in his generation. The phrase "son of heaven" is not typically used in the context of Noah; however, he is often viewed as a chosen figure by God to preserve humanity and creation through the flood.
