76 The word זֵד (zed, “proud”) comes from the verb זִיד (zid, “to boil up; to seethe; to act proudly [or, presumptuously].” Just as water boiling up in a pot will boil over, so the presumptuous person “oversteps” the boundaries.
77 The word יָהִיר (yahir) means “haughty,” that is, to be or show oneself to be presumptuous or arrogant.
78 Heb “proud haughty scorner his name” ( similar). There are several ways that the line could be translated: (1) “Proud, arrogant—his name is scoffer” or (2) “A proud person, an arrogant person—‘Scoffer’ is his name.” 267 זֵד suggests, “A presumptuous man, [who is] haughty, scoffer is his name.”
79 Heb “does.” The Qal active participle “does” serves as the main verb, and the subject is “proud person” in the first line.
80 The expression בְּעֶבְרַת זָדוֹן (be’evrat zadon) means “in the overflow of insolence.” The genitive specifies what the overflow is; the proud deal in an overflow of pride. Cf. “overweening pride”; “boundless arrogance.” The portrait in this proverb is not merely of one who is self-sufficient, but one who is insolent, scornful, and arrogant.
