Carl Friedrich Keil and Franz Delitzsch Old Testament Commentary

המיּות (plur. of הומי, the ground-form of הומה, from המי = המה), "they who are making noise;" for the epithet is poetically used (Isa 22:2) as a substantive, crowded noisy streets or places. ראשׁ is the place from which on several sides streets go forth: cf. ras el-ain, the place where the well breaks forth; ras en-nahr, the place from which the stream divides itself; the sing. is meant distributively as little as at Pro 8:2. פּתח, if distinguished from שׁער (which also signifies cleft, breach), is the opening of the gate, the entrance by the gate. Four times the poet says that Wisdom goes forth preaching, and four times that she preaches publicly; the בּעיר used in five places implies that Wisdom preaches not in the field, before the few who there are met with, but in the city, which is full of people.
