And God did for Sarah as he had spoken, at the set time that God had told him of. And Abraham named his newborn son, whom Sarah had borne to him, Isaac. And when Isaac was eight days old, Abraham circumcised him, as God had commanded him. And Abraham was a hundred years old when his son Isaac was born.
Some time later, Abraham was told that Milcah too had borne sons to his brother Nahor: Uz the firstborn, his brother Buz, and Kemuel, the father of Aram, and Chesed, Hazo, Pildash, Jidlaph, and Bethuel. These eight Milcah bore to Nahor, Abraham’s brother. And his concubine, whose name was Reumah, also bore sons: Tebah, Gaham, Tahash, and Maacah.
And Abraham took another wife, whose name was Keturah. And she bore him Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. And Jokshan fathered Sheba and Dedan. And the descendants of Dedan became the Asshurites, the Letushites, and the Leummites. And the sons of Midian were Ephah, Epher, Enoch, Abida, and Eldaah. All these were the descendants of Keturah.
