פירוש על בראשית 10:6

ופוט וכנען, the sons of Put are not mentioned separately, as they all formed a single nation retaining the name of their founding father. Proof of this is found in Ezekiel 38,5 פרס, כוש, ופוט אתם, i.e. even in the days of the pre-messianic wars of Gog and Magog, Put will still have its original name.

ובני חם, Cham is mentioned after Yaphet; if Yaphet was the junior of the three sons, he was mentioned ahead of Cham because of his superior character qualities. If he was older than Cham, he would qualify for earlier mention on that account alone. The Torah left the list of the descendants of Shem last, in order to preserve the continuity of the report which continues with the lives of the patriarchs who are all descendants of Shem.
