וחם הוא אבי כנען. לָמָּה הֻצְרַךְ לוֹמַר כָּאן? לְפִי שֶׁהַפָּרָשָׁה עֲסוּקָה וּבָאָה בְּשִׁכְרוּתוֹ שֶׁל נֹחַ שֶׁקִּלְקֵל בָּה חָם וְעַל יָדוֹ נִתְקַלֵּל כְּנַעַן, וַעֲדַיִן לֹא כָתַב תּוֹלְדוֹת חָם, וְלֹא יָדַעְנוּ שֶׁכְּנַעַן בְּנוֹ – לְפִיכָךְ הֻצְרַךְ לוֹמַר כָּאן וְחָם הוּא אֲבִי כְנָעַן:

וחם הוא אבי כנען AND HAM IS THE FATHER OF CANAAN — Why is it necessary to mention this here? Because this section goes on to deal with the account of Noah’s drunkenness when Ham sinned and through him Canaan was cursed. Now as the generations of Ham have not yet been mentioned and we therefore would not know that Canaan was his son, it was necessary to state here that “Ham is the father of Canaan”.
