Abram thought to leave his estate to a trusted servant, but God promised him a son and heir.
[3] In Genesis 17, "Almighty God" changed Abram’s name to Abraham, for he would be a father of many nations.
Abraham then married Keturah, who bore him six more sons – Zimran, Jokshan, Medan, Midian, Ishbak and Shuah.
For example, one English translation of the Bible states in Genesis 11:13 that "After the birth of Shelah, Arphachshad lived 403 years and begot sons and daughters."
"[4] Some other children, such as Cainan, are only described in later translations that are not considered part of the original, canonical text of the Hebrew Bible.
