Origin of Benjamin’s King Saul

1 Chronicles 8:1-40
    1 Now Benjamin begot Bela his firstborn, Ashbel the second, Aharah the third, 2 Nohah the fourth, and Rapha the fifth. 3 The sons of Bela were Addar, Gera, Abihud, 4 Abishua, Naaman, Ahoah, 5 Gera, Shephuphan, and Huram.
    6 These are the sons of Ehud, who were the heads of the fathers' houses of the inhabitants of Geba, and who forced them to move to Manahath: 7 Naaman, Ahijah, and Gera who forced them to move. He begot Uzza and Ahihud.
    8 Also Shaharaim had children in the country of Moab, after he had sent away Hushim and Baara his wives. 9 By Hodesh his wife he begot Jobab, Zibia, Mesha, Malcam, 10 Jeuz, Sachiah, and Mirmah. These were his sons, heads of their fathers' houses.
    11 And by Hushim he begot Abitub and Elpaal. 12 The sons of Elpaal were Eber, Misham, and Shemed, who built Ono and Lod with its towns; 13 and Beriah and Shema, who were heads of their fathers' houses of the inhabitants of Aijalon, who drove out the inhabitants of Gath. 14 Ahio, Shashak, Jeremoth, 15 Zebadiah, Arad, Eder, 16 Michael, Ispah, and Joha were the sons of Beriah. 17 Zebadiah, Meshullam, Hizki, Heber, 18 Ishmerai, Jizliah, and Jobab were the sons of Elpaal. 19 Jakim, Zichri, Zabdi, 20 Elienai, Zillethai, Eliel, 21 Adaiah, Beraiah, and Shimrath were the sons of Shimei. 22 Ishpan, Eber, Eliel, 23 Abdon, Zichri, Hanan, 24 Hananiah, Elam, Antothijah, 25 Iphdeiah, and Penuel were the sons of Shashak. 26 Shamsherai, Shehariah, Athaliah, 27 Jaareshiah, Elijah, and Zichri were the sons of Jeroham.

    28 These were heads of the fathers' houses by their generations, chief men. These dwelt in Jerusalem.

    29 Now the father of Gibeon, whose wife's name was Maacah, dwelt at Gibeon. 30 And his firstborn son was Abdon, then Zur, Kish, Baal, Nadab, 31 Gedor, Ahio, Zecher, 32 and Mikloth, who begot Shimeah. They also dwelt alongside their relatives in Jerusalem, with their brethren. 33 Ner begot Kish, Kish begot Saul, and Saul begot Jonathan, Malchishua, Abinadab, and Esh-Baal. 34 The son of Jonathan was Merib-Baal, and Merib-Baal begot Micah. 35 The sons of Micah were Pithon, Melech, Tarea, and Ahaz. 36 And Ahaz begot Jehoaddah; Jehoaddah begot Alemeth, Azmaveth, and Zimri; and Zimri begot Moza. 37 Moza begot Binea, Raphah his son, Eleasah his son, and Azel his son.
    38 Azel had six sons whose names were these: Azrikam, Bocheru, Ishmael, Sheariah, Obadiah, and Hanan. All these were the sons of Azel. 39 And the sons of Eshek his brother were Ulam his firstborn, Jeush the second, and Eliphelet the third.  40 The sons of Ulam were mighty men of valor—archers. They had many sons and grandsons, one hundred and fifty in all. These were all sons of Benjamin.

Descendants of the tribe of Benjamin, the line of king Saul (in verse 33) are described in chapter 8 (Gen. 46:21).  There were more mighty men of valor, some living in Jerusalem and some living in other cities.  Each family line is traced as to where they went to validate the historic accuracy of the scriptures and set the stage to later identify some who are mentioned later in other parts of the written word of the LORD.  These sons of Benjamin are important especially to define who king Saul, the first king of Israel, was and where he came from.  The testimony of scripture is reliable and accurate, words we can trust in for the entire narrative from the fall of man to his redemption and future glorification not yet seen (Romans 8:23, 25, Philippians 3:20-21, Luke 1:1, 3-4).
