Amasa

Amasa (Hebrew: עמשא) or Amessai is a person mentioned in the Hebrew Bible. His mother was Abigail (2 Samuel 17:25), a sister of King David (1 Chronicles 2:16,17). Hence, Amasa was a nephew of David, and cousin of Joab, David's military commander, as well as a cousin of Absalom, David's son. David calls him "my bone and my flesh" (2 Samuel 19:13).
