(1) The eldest son of David and Ahinoam, the Jezreelites (compare 2 Samuel 3:2). As the crown prince and heir presumptive to the throne, he was intensely hated by Absalom, who was, therefore, doubly eager to revenge the outrage committed by Amnon upon his sister Tamar (2 Samuel 3:2; 13:1 ff, 1 Chronicles 3:1).

(2) A name in the genealogy of Judah (1 Chronicles 4:20).
