2 Samuel 24:9 - Joab gave up the sum of the numbering of the people to the king: and there were in Israel eight hundred thousand valiant men who drew the sword; and the men of Judah were five hundred thousand men.
2 Samuel 11:1 - 27 - It happened, at the return of the year, at the time when kings go out, that David sent Joab, and his servants with him, and all Israel; and they destroyed the children of Ammon, and besieged Rabbah. But David stayed at Jerusalem. It happened at evening, that David arose from off his bed, and walked on the roof of the king's house: and from the roof he saw a woman bathing; and the woman was very beautiful to look on. David sent and inquired after the woman. One said, "Isn't this Bathsheba, the daughter of Eliam, the wife of Uriah the Hittite?" David sent messengers, and took her; and she came in to him, and he lay with her (for she was purified from her uncleanness); and she returned to her house. The woman conceived; and she sent and told David, and said, "I am with child." David sent to Joab, "Send me Uriah the Hittite." Joab sent Uriah to David. When Uriah had come to him, David asked of him how Joab did, and how the people fared, and how the war prospered. David said to Uriah, "Go down to your house, and wash your feet." Uriah departed out of the king's house, and a gift from the king was sent after him. But Uriah slept at the door of the king's house with all the servants of his lord, and didn't go down to his house. When they had told David, saying, "Uriah didn't go down to his house," David said to Uriah, "Haven't you come from a journey? Why didn't you go down to your house?" Uriah said to David, "The ark, Israel, and Judah, are staying in tents; and my lord Joab, and the servants of my lord, are encamped in the open field. Shall I then go into my house to eat and to drink, and to lie with my wife? As you live, and as your soul lives, I will not do this thing!" David said to Uriah, "Stay here today also, and tomorrow I will let you depart." So Uriah stayed in Jerusalem that day, and the next day. When David had called him, he ate and drink before him; and he made him drunk. At evening, he went out to lie on his bed with the servants of his lord, but didn't go down to his house. It happened in the morning, that David wrote a letter to Joab, and sent it by the hand of Uriah. He wrote in the letter, saying, "Send Uriah to the forefront of the hottest battle, and retreat from him, that he may be struck, and die." It happened, when Joab kept watch on the city, that he assigned Uriah to the place where he knew that valiant men were. The men of the city went out, and fought with Joab. Some of the people fell, even of the servants of David; and Uriah the Hittite died also. Then Joab sent and told David all the things concerning the war; and he commanded the messenger, saying, "When you have finished telling all the things concerning the war to the king, it shall be that, if the king's wrath arise, and he asks you, `Why did you go so near to the city to fight? Didn't you know that they would shoot from the wall? who struck Abimelech the son of Jerubbesheth? Didn't a woman cast an upper millstone on him from the wall, so that he died at Thebez? Why did you go so near the wall?' then you shall say, `Your servant Uriah the Hittite is dead also.'" So the messenger went, and came and showed David all that Joab had sent him for. The messenger said to David, "The men prevailed against us, and came out to us into the field, and we were on them even to the entrance of the gate. The shooters shot at your servants from off the wall; and some of the king's servants are dead, and your servant Uriah the Hittite is dead also." Then David said to the messenger, "Thus you shall tell Joab, `Don't let this thing displease you, for the sword devours one as well as another. Make your battle stronger against the city, and overthrow it.' Encourage him." When the wife of Uriah heard that Uriah her husband was dead, she made lamentation for her husband. When the mourning was past, David sent and took her home to his house, and she became his wife, and bore him a son. But the thing that David had done displeased Yahweh.
2 Samuel 17:25 - Absalom set Amasa over the army instead of Joab. Now Amasa was the son of a man, whose name was Ithra the Israelite, who went in to Abigail the daughter of Nahash, sister to Zeruiah, Joab's mother.
1 Chronicles 21:5 - Joab gave up the sum of the numbering of the people to David. All those of Israel were one million one hundred thousand men who drew sword: and in Judah were four hundred seventy thousand men who drew sword.
2 Samuel 14:31 - Then Joab arose, and came to Absalom to his house, and said to him, "Why have your servants set my field on fire?"
