The Lord sustains, one of David’s heroes (1 Chr. 11:29), general of the eighth division of the army (27:11). He slew the giant Saph in the battle of Gob (2 Sam. 21:18; R.V., “Sibbechai”). Called also Mebunnai (23:27).
Sibbecai
Sibbecai the Hushathite is one of the soldiers around King David, and his name is spelled two ways in the KJV, here and as Sibbechai. In two battles with the Philistines he strikes down a descendant of the giants: Saph at Gob (2 Samuel 21:18) and Sippai at Gezer (1 Chronicles 20:4). He is also listed among David’s mighty men (1 Chronicles 11:29) and named as captain of a division of twenty and four thousand for the eighth month (1 Chronicles 27:11). Scripture does not say much more, but it records him by name.
