The name that is transliterated as «Hathach» in English means «terror,» «casting down,» «bruised.» (Source: Cornwall / Smith 1997 )
In Libras (Brazilian Sign Language) it is translated with a sign that combines “true” (he was a eunuch officer responsible for serving Esther) with the movement and joint points of an officer. (Source: Missão Kophós )
