Bigvai 1.
2056 (Ezra 2:14), 2067 (Nehemiah 7:19), children of Bigvai returned from Babylon with Zerubbabel; 72 subsequently with Ezra (Ezra 8:14). The different circumstances under which the two registers were made account for the variation of numbers: Ezra's in Babylon, Nehemiah's in Judaea, after the walls had been built. Many, who intended to return and were so put down in the former list, were prevented by death, or changed their minds and stayed. Many, not entered in it, afterward joined the caravan when starting. The variation is a plain proof of the absence of collusion between the two writers.
2.A chief of Zerubbabel's expedition, who subsequently signed the covenant (Ezra 2:2; Nehemiah 7:7).
