Genesis 22:15-24

Then the angel of the LORD called again to Abraham from heaven. “This is what the LORD says: Because you have obeyed me and have not withheld even your son, your only son, I swear by my own name that I will certainly bless you. I will multiply your descendants beyond number, like the stars in the sky and the sand on the seashore. Your descendants will conquer the cities of their enemies. And through your descendants all the nations of the earth will be blessed—all because you have obeyed me.” Then they returned to the servants and traveled back to Beersheba, where Abraham continued to live. Soon after this, Abraham heard that Milcah, his brother Nahor’s wife, had borne Nahor eight sons. The oldest was named Uz, the next oldest was Buz, followed by Kemuel (the ancestor of the Arameans), Kesed, Hazo, Pildash, Jidlaph, and Bethuel. (Bethuel became the father of Rebekah.) In addition to these eight sons from Milcah, Nahor had four other children from his concubine Reumah. Their names were Tebah, Gaham, Tahash, and Maacah.
