Amminadib in the Bible Encyclopedia - ISBE

a-min'-a-dib (`amminadhibh): The name occurs in the King James Version and the Revised Version, margin only in one passage (Song 6:12, "the chariots of Amminadib"). In King James Version margin and the Revised Version (British and American) text, however, it is not regarded as a proper name, and the clause is rendered, "among the chariots of my princely people." Interpretations widely vary (see COMMENTARIES).
