Amasa in the Bible Encyclopedia - ISBE
a-ma'-sa (`amasa', or read `ammishai, i.e. `am yishai,
"people of Jesse"): The form `amasa', is based upon a
mistaken etymology (from = `amac "to burden").
(1) According to 2 Sam 17:25, Amasa is the son of Abigail,
the sister of Zeruiah and David, and Ithra, an Israelite;
but another source, 1 Ch 2:17, calls his father Jether the
Ishmaelite. He was a nephew of David and a cousin of
Absalom, who made him commander of the army of rebellion.
When the uprising had been quelled, David, in order to
conciliate Amasa, promised him the position held by Joab;
the latter had fallen from favor (2 Sam 19:13 ff). When a
new revolt broke out under Sheba, the son of Bichri (2 Sam
20), Amasa was entrusted with the task of assembling the men
of Judah. But Joab was eager for revenge upon the man who
had obtained the office of command that he coveted. When
Amasa met Joab at Gibeon, the latter murdered him while
pretending to salute (2 Sam 20:8-10; 1 Ki 2:5).
(2) Son of Hadlai, of the Bene 'Ephrayim ("Children of
Ephraim"), who, obeying the words of the prophet Oded,
refused to consider as captives the Judeans who had been
taken from Ahaz, king of Judah, by the victorious Israelites
under the leadership of Pekah (2 Ch 28:12).
