( 1 Chronicles 11:29;  1 Chronicles 27:11) or Sib'bechai ( 2 Samuel 21:18;  1 Chronicles 20:4) [some Sibbeca'i and Sibbecha'i] (Heb. Sibbekay', סַבְּכִי , according to Gesenius and Furst for סֶבֶךְ יָהּ , thicket [i.e. people] Of Jehovah, Or Jehovah is A Thicket [i.e. defense]; but rather a Weaver, for it is doubtful if the final י in such cases ever stands for the sacred name; Sept. Σοβοχαί v.r. Σεβοχά , etc.; Josephus Σοβακχίς ), the eighth named of the subordinate thirty in David's guard, and eighth captain for the eighth month of 24,000 men of the king's army ( 1 Chronicles 11:29;  1 Chronicles 27:11). B.C. 1043. He belonged to one of the principal families of Judah, the Zarhites, or descendants of Zerah, and is called "the Hushathite," probably from an ancestor by the name of Hushah (q.v.). Josephus ( Ant. 7, 12, 2) calls him "the Hittite," but this is no doubt an error. Sibbecai's great exploit, which gave him a place among the mighty mean of David's army, was his single combat with Saph, or Sippai, the Philistine giant, in the battle at Gezer, or Gob ( 2 Samuel 21:18;  1 Chronicles 20:4). In  2 Samuel 23:27 his name is written MEBUNNAI by a mistake of the copyist. Josephus says that he slew "many" who boasted that they were of the descent of the giants, apparently reading רבי for ספי in  1 Chronicles 20:4.
