וַיִּוָּלֵ֤ד לַֽחֲנוֹךְ֙ אֶת־עִירָ֔ד וְעִירָ֕ד יָלַ֖ד אֶת־מְחֽוּיָאֵ֑ל וּמְחִיּיָאֵ֗ל יָלַד֙ אֶת־מְת֣וּשָׁאֵ֔ל וּמְתוּשָׁאֵ֖ל יָלַ֥ד אֶת־לָֽמֶךְ׃
און בײַ חַנוכן איז געבאָרן געװאָרן עִירָד, און עִירָד האָט געבאָרן מחױָאֵלן, און מחױָאֵל האָט געבאָרן מתושָאֵלן, און מתושָאֵל האָט געבאָרן לֶמֶכן.
Rashi
הנפילים THE GIANTS — Thy were called נפילים because they fell (נפלו) and caused the downfall of (הפילו) the world (Genesis Rabbah 26:7).

וגם אחרי כן AND ALSO AFTER THAT — Although they witnessed the destruction of the generation of Enosh when the Ocean rose and flooded a third part of the world, yet the generation of the Flood did not humble itself and take a lesson from them (Genesis Rabbah 26).
Rashi
אשר יבאו WHEN [THE SONS OF GOD] CAME IN, they (the women) bore children, giants like them (the fathers) (Genesis Rabbah 26:7).
Rashi
אנשי שם MEN OF RENOWN (literally, men of name) — Men who bore distinctive names: עירד, מחויאל, מתושאל being so named because these names have reference to their destruction, for they were wiped out and torn out from the world (מחוי-אל would signify “wiped-out-by-God”, מתושאל “Torn-out-by-God). Another explanation is that they were men of devastation (אנשי שם-מון) — who devastated the world (Genesis Rabbah 26:7).
