The headword, a nominative plural, is evidently quoted from somewhere; possibly Josephus, Jewish Antiquities 3.9 (though the glossing implies other contexts as well or instead).
[1] See also Etymologicum Genuinum, and Etymologicum Magnum 806.24. The first of these reads δίφροι ("chariots" or "seats") for the Suda's δίφριοι ("[things] of a chariot"). The quotation which follows the gloss clearly pertains to chariots, but δίφροι is perhaps to be preferred as χαμαίζηλοι is also a word for low stools. See also Erotion 94.7.
[2] The source of this quotation is unknown and the quotation itself is omitted by Adler's manuscript F (Laurentianus 55.1)
