- Why did Noah have children only at the age of 500 years? G-d did not let him have children until that time, so that Japheth, his eldest son, should not be liable for punishment before the Flood, as it is written (Isa. 65:20):“For the youth who is one hundred years old shall die.”
- Shem, Ham, and Japheth. Now was not Japheth the eldest? [i.e., Why is he mentioned last?] But first you talk about the one who was righteous, born circumcised, and from whom Abraham was descended, etc. — [from Gen. Rabbah 26:3]
