Without citing the whole text, my question simply is: Is v.16 a further reason for v.12, 13 (as v.14 seems to be) and therefore v.15 is a parentesis. Or, of v.16 a reason for v.15 - my question has to do with grammar, that is, are there grammatical answers to my questions. V.14 ...GAR V.15 EI DE V.16 ... GAR Thanks, Francisco Orozco
