Joab

Joab (Hebrew יוֹאָב‎ _ModernYo'av _Tiberian Yôʼāḇ) the son of Zeruiah, was the nephew of King David and the commander of his army, according to the Bible.

The name Joab (יוֹאָב‎) is derived from Yahweh (יהוה‎), the name of the God of Israel, and the Hebrew word 'av' (אָב‎), meaning 'father'. It therefore means 'Yahweh [is] father'. Apart from David's nephew, the name is given to two other individuals in the Bible (see Ezra 2:6, 8:9). Those are the descendants of Joab of Bethlehem the son of Zeruiah; the subject is of the house and head of the house. The individual is Obadiah the son of Jehiel. It is also a common name in modern Israel.

The name Yoav (Joab) may also be attributed to the district of Moav (Moab in Latin transcription),eastern bank of the Jordan, from where Ruth the Moabitess came.

Joab was the son of Zeruiah, a sister of king David, who made him captain of his army (2 Samuel 8:16; 20:23; 1 Chronicles 11:6; 18:15; 27:34). He had two brothers, Abishai and Asahel. Asahel was killed by Abner in combat, for which Joab took revenge by murdering Abner in an ambush against David's wishes (2 Samuel 2:13-32; 3:27).
