They could have made a mistake, or they could have been quoting to Herod a Greek translation besides the Septuagint. More likely though, they could have been translating from Hebrew to Aramaic or Greek verbally as they were going along.
Huenda walifanya makosa au walinukuu kwa Herode tafsiri ya Kigiriki mbali ya Septuagint. Lakini jambo ambalo lina uwezekano mkubwa zaidi ni kuwa walikuwa wanatafsiri kutoka Kiebrania kwenda Kiaramu au Kigiriki kwa kuzungumza walipokuwa wanatembea.
