Abishai in Fausset's Bible Dictionary
("father of gifts".) Nephew of David by his sister Zeruiah;
brother of Joab and Asahel. Joab was more of the experienced
general, Abishai the devoted champion for David. Thus, when
David proposed to Ahimelech the Hittite and Abishai the
perilous visit to Saul's camp, Abishai instantly
volunteered, reckless of personal danger. His impulsive
nature needed occasional checking, in his zeal for David. We
find the consistency of character maintained throughout the
history; the same spirit prompting the request at Hachilah,"
Let me smite Saul" (1 Samuel 26:8), as subsequently at
Bahurim, when Shimei cursed David, prompted his exclamation
"Why should this dead dog curse my Lord the king? let me
take off his head" (2 Samuel 16:9).
He commanded one third of David's army at the battle with
Absalom (2 Samuel 18), and rescued David when waxing faint
and in imminent peril from the giant Ishbi-benob (2 Samuel
21:15-17). In the same war probably he, as chief of the
three "mighties," chivalrously broke through the Philistine
host to procure water for David from the well of his native
Bethlehem (2 Samuel 23:14-17). Once he withstood 300 and
slew them with his spear. In 2 Samuel 8:13 the victory over
the 15,000 Edomites or Syrians in the Valley of Salt is
ascribed to David; in 1 Chronicles 18:12, to Abishai.
Probably the commander in chief was David, but the victory
actually gained by Abishai.
