Abraham marries Keturah, has six children with her, and has more children with his concubines. “And Abraham gave all that he had to Isaac. But Abraham gave gifts to the sons of the concubines which Abraham had; and while he was still living he sent them eastward, away from Isaac his son, to the country of the east.”
God keeps His promise to make you a great nation to Ishmael, Abraham’s son born by Hagar. Ishmael lives “one hundred and thirty-seven years; and he breathed his last and died, and was gathered to his people. (They dwelt from Havilah as far as Shur, which is east of Egypt as you go toward Assyria.) He died in the presence of all his brethren.”
However, the story continues through the promised son Isaac. When Rebekah is unable to conceive, Isaac and Rebekah do not take matters into their own hands like Abraham and Sarah. Instead, Isaac pleads to the Lord on behalf of his wife. The Lord hears his prayers and opens his wife’s womb. Isaac and Rebekah have twins, Esau and Jacob, who begin fighting as early as in the womb. The Lord tells Rebekah that the older, Esau, will serve the younger, Jacob. We will learn that this family is extremely messy, but God is going to continue fulfilling His plan of sending a Savior to redeem broken and messy people through Isaac’s son Jacob.
We end the reading with the death of Abraham. Abraham dies having eight named descendants plus other children by his concubines, a piece of burial land, and promises from the Lord that He would make him a great nation, kings would come from him, and all the families of the earth would be blessed through him. God always does what He says He is going to do; although we might not see it played out on this side of heaven. But we are fortunate enough to get to read His promises, so keep reading!
