[1] Same glossing in ps.-Zonaras, and equivalently (for nominative plurals) in the Lexicon Vindobonense. See also a scholion on Homer, Iliad 11.700, where the infinitive qeu/sesqai occurs, and likewise in Apollonius' Homeric Lexicon, Hesychius, and the Etymologicum Magnum.
The headword, presumably extracted from the quotation given, is a "Doric" (see Smyth §540: web address 1) future middle participle, masculine nominative singular, of qe/w.
[2] Quotation unidentifiable. (For the one-lap race, stadion, cf. under delta 807.)
