251 Abraham married a second time; his new wife was named Keturah. 2 She gave birth to Zimran, Jokshan, Medan, Midian, Ishbak, and Shuah. 3 Jokshan had Sheba and Dedan. Dedan's descendants were the Asshurim, the Letushim, and the Leummim. 4 Midian had Ephah, Epher, Hanoch, Abida, and Eldaah - all from the line of Keturah. 5 But Abraham gave everything he possessed to Isaac. 6 While he was still living, he gave gifts to the sons he had by his concubines, but then sent them away to the country of the east, putting a good distance between them and his son Isaac.

Commentary on Genesis 25:1-10
(Read Genesis 25:1-10)
All the days, even of the best and greatest saints, are not remarkable days; some slide on silently; such were these last days of Abraham. Here is an account of Abraham's children by Keturah, and the disposition which he made of his estate. After the birth of these sons, he set his house in order, with prudence and justice. He did this while he yet lived. It is wisdom for men to do what they find to do while they live, as far as they can. Abraham lived 175 years; just one hundred years after he came to Canaan; so long he was a sojourner in a strange country. Whether our stay in this life be long or short, it matters but little, provided we leave behind us a testimony to the faithfulness and goodness of the Lord, and a good example to our families. We are told that his sons Isaac and Ishmael buried him. It seems that Abraham had himself brought them together while he lived. Let us not close the history of the life of Abraham without blessing God for such a testimony of the triumph of faith.
