The name that is transliterated as «Amminadab» in English means «my liberal people,» «my people are willing,» «my kinsman is generous.» (Source: Cornwall / Smith 1997 )
In Libras (Brazilian Sign Language) it is translated with a sign that combines the number 3 (Amminadab is a descendant of Judah and Judah is the third listed tribe) and for his son Nahshon who was a prince of the tribe of Judah. (Source: Aline Martins and Paul Fahnestock)
