"And Absalom made Amasa captain of the host instead of Joab: which Amasa {was} a man's son, whose name {was} Ithra an Israelite, that went in to Abigail the daughter of Nahash, sister to Zeruiah Joab's mother. {Ithra an Israelite: or, Jether an Ishmaelite} {Abigail: Heb. Abigal} {Nahash: or, Jesse}"
