Ba'ainah (Hebrews Baanak', בִּעֲנָה, another form of the name Baani [q.v.]; Sept. Βαανά.), the name of four men.
1. One of the two sons of Rimmon the Beerothite, captains of bands in Saul's army, who assassinated Ishbosheth (2Sa 4:2); for which murder they were slain by David, and their mutilated bodies hung up over the pool at Hebron (ver. 5, 6, 19). B.C. 1046. Josephus represents him (Βαναόθα, Ant. 7, 2, 1) as a person of noble family, and instigated by personal ambition. SEE DAVID.
2. A Netophathite, father of Heleb or Heled, which latter was one of David's thirty heroes (2Sa 23:29; 1Ch 11:30). B.C. ante 1061. The Sept. utterly confounds the list of names at this part, but some copies retain the Βαανά.
3. (1Ki 4:16.) SEE BAANA, 2.
4. One of the chief Jews who returned from Babylon with Zerubbabel, B.C. 536 (Ezr 2:2; Ne 7:7); possibly the same with one of those who long afterward (B.C. 410) united in the sacred covenant with Nehemiah (Ne 10:27).
