Same entry in other lexica; references at Photius alpha1311 Theodoridis. The headword is an Homeric epithet -- more properly spelled a)mfi/guos -- of the noun e)/gxos (lance, spear): either "with a limb at each end" (if from gui=on) or "bending both ways" (if from gu/hs). It is glossed here as in the scholia to Homer, Iliad 13.147, from where it is taken to be quoted. It occurs only, as here, in the dative plural, and only in formulaic phrases.
