Whom the Lord sets up, one of those “which came with Zerubbabel” (Ezra 2:13). His “children,” or retainers, to the number of 666, came up to Jerusalem (8:13).

ad-o-ni'-kam ('adhoniqam, "my lord has risen up"): The name of a family of the returning exiles (Ezr 2:13; Ne 7:18). "The sons of Adonikam," men and women and children, numbered 666 according to the list as given in Ezr, but 667 according to the copy in Neh. Either included among these or in addition to them was the contingent that came with Ezr, "Ehphalet, Jeuel, and Shemaiah, and with them 60 males" (Ezr 8:13).
