Jashobeam

Three hundred men struck down at one time by a single soldier’s spear: that is the deed credited to Jashobeam. First Chronicles lists him at the head of David’s mighty men and calls him “the chief of the captains.” The parallel list in 2 Samuel tells a similar story, though the name and the number there are different. A Jashobeam is also named among the Korhites in another roll in Chronicles. The verses give his rank and one remembered act, and little else, as lists of the brave often do.

From Easton's Bible Dictionary

Matthew George Easton, 1897

Dweller among the people; or to whom the people turn, the Hachmonite (1 Chr. 11:11), one of David’s chief heroes who joined him at Ziklag (12:6). He was the first of the three who broke through the host of the Philistines to fetch water to David from the well of Bethlehem (2 Sam. 23:13-17). He is also called Adino the Eznite (8).

From Smith's Bible Dictionary

William Smith, 1884

(to whom the people turn), named first among the chief of the mighty men of David. (1 Chronicles 11:11) (B.C. 1046.) He came to David at Ziklag. His distinguishing exploit was that he slew 300 (or 800,) (2 Samuel 23:8) men at one time.
