hermeneutics.stackexchange.com/a/8570/2873 Please just tell me how this comment is incorrect. Noah was 599 years old at the start of the flood. If it’s accepted that Shem was 500 years younger (per Gen 5:32), Shem would have been 99 at the start of the flood; 2 years later he would have been beyond the 100 years old at 101. (Gen 5:32 And Noah was five hundred years old: and Noah begat Shem, Ham, and Japheth.) Thanks.
