The headword is present indicative active, third person singular, of the verb dorufore/w, literally 'carry a spear' or 'be a spear-carrier'. (For the noun cognate with this verb see delta 1403.) It must be quoted from somewhere.
[1] i.e. accusative of the person(s) or thing(s) attended. (According to Adler there are comparable entries in Anecdota Graeca (Oxford) 4.290.32 Cramer and the Lexicon Syntacticum of codex Laurentianus 59.16.) LSJ s.v. cites instances from Herodotus (2.168.2, 3.127.1) and Thucydides (1.130.1) onwards.
[2] = Synagoge delta351; Photius, Lexicon delta726. Presumably the idea is that attending to someone or something as a bodyguard would attend him/her/it ennobles the person or thing attended. For such (or a similar) figurative sense of doruforei= itself one needs to look as late as the third century CE, and the Orations of Themistius of Constantinople (e.g. 36d4 and 67b3 Harduin); but more generally the usage can be traced back to the fourth century BCE, with Isocrates 10.37 (on Theseus: diete/lese to\n bi/on ... th|= tw=n politw=n eu)noi/a| doruforou/menos).
