The name that is transliterated as «Hegai» in English means «venerable,» «a speaker,» «my meditations.» (Source: Cornwall / Smith 1997 )
In Libras (Brazilian Sign Language) it is translated with a sign that combines the signs for “official” (he was an official of the king) and “eunuch.” (Source: Missão Kophós )
