No equivalent entry in other lexica. The headword is present indicative active, third person plural, of diei/rw. It must be extracted from somewhere -- probably Aeschines 3.166 (purporting to quote an image used by his opponent Demosthenes), a passage famous enough to be repeated by Dionysius of Halicarnassus. Alternatives are few but include Xenophon, Cyropaedia 8.3.10. (The glossing is rather odd in any event, however.)
