Ingawa kitabu cha mwenye kushuku kiitwacho Asimov’s Guide to the Bible, uk.597 kinadai, "sehemu nyingine za lugha zisizoeleweka kwa urahisi zilizotumiwa zinaonyesha kipindi cha Kigiriki tofauti na kile cha uhamisho wa Babeli", kuna maneno matatu tu ya Kigiriki kwenye Kitabu cha Daniel, ambayo ni kidogo kuliko maneno saba ya Kiajemi yaliyomo.
