XXbin-u-i (binnuy, a proper name, "a building up"):
(1) A Levite, living in the time of Ezra (Ezr 8:33; Neh 10:9; 12:8).
(2) One of the bene Pachath-moabh who had taken foreign wives (Ezr 10:30--Balnuus of 1 Esdras 9:31) and one of the bene Bani (Ezr 10:38) who had also intermarried.
(3) The son of Henadad, who built part of the wall of Jerusalem (Neh 3:24), and sealed the covenant with Nehemiah (Neh 10:9). In all probability he is identical with "Bavvai, the son of Henadad" mentioned in Neh 3:18. "Bavvai" is either a corruption of "Binnui," or is the name of the Levitical house of which Bavvai was the chief representative. Binnui is mentioned in Neh 10:9 as a leading Levite, and, besides, the names in these verses are obviously those of priests and Levites; so the former theory is probably correct.
(4) Head of a family who returned with Zerubbabel (Neh 7:15; Ezr 2:10).
