It turns out, the story continues in some fascinating, and sometimes surprising, ways.

According to Ginzberg's retelling in Legends of the Jews, Rebekah first saw Isaac returning from Beer-lahai-roi, the "well of the Living One who sees me," a place associated with Hagar. Why was he there? Well, after the death of his mother Sarah, Isaac had gone there to reunite his father with Hagar, who is also known as Keturah. Yes, Abraham and Hagar were together again!

And here's where the story takes another unexpected turn. Hagar bore Abraham six more sons. But these sons, alas, didn't exactly follow in their father's monotheistic footsteps. They were, as the text puts it, all idolaters.

So, what did Abraham do? Knowing that Isaac was his chosen heir, he sent these sons away during his own lifetime, "that they might not be singed by Isaac's flame," meaning that they wouldn't be consumed by the spiritual power and destiny associated with Isaac. He instructed them to journey eastward, as far as possible.

And this is where it gets really interesting. Abraham, according to the legend, built them a city surrounded by an iron wall, so high that the sun couldn't penetrate it. Now, that sounds pretty bleak, right? But Abraham didn't leave them in total darkness. He provided them with huge gems and pearls, whose brilliance outshone the sun. These gems, it's said, will be used in the Messianic time, "when 'the moon shall be confounded and the sun ashamed.'" (Isaiah 24:23).

But there's more. Abraham also taught them the black art! Yes, you read that right. He taught them sorcery, enabling them to control demons and spirits. It’s said that Laban, Balaam, and Balaam's father Beor all derived their sorceries from this city in the east. Talk about a family legacy!

One of Abraham and Keturah's grandsons, Epher, even invaded Lybia and took possession of the country. And from this Epher, the whole land of Africa supposedly gets its name.

The story expands even further, branching out into the origins of other nations and peoples. In his old age, Terah, Abraham's father, remarried and had a son named Zoba, who in turn had three sons. The eldest, Aram, became incredibly wealthy and powerful. He and his kinsmen, the sons of Nahor (Abraham's brother), found their old home in Haran too small, so they migrated and built a city called Aram-Zoba. Another Aram, Aram-naharaim, on the Euphrates, was built by Aram son of Kemuel, a nephew of Abraham. Its real name was Petor, after the son of Aram, but it is better known as Aram-naharaim. And the descendants of Kesed, another nephew of Abraham, established themselves opposite Shinar, founding the city of Kesed, from which the Chaldeans are called Kasdim.

Now, with all these sons and descendants, what about Isaac? Abraham knew that Isaac deserved his paternal blessing, but he withheld it, wanting to avoid any conflict or resentment among his descendants. He essentially said, "I've done what I can. Let God's will be done." And immediately after Abraham's death, God Himself appeared to Isaac and gave him His blessing.

What does this all mean? It’s a reminder that even the lives of our greatest ancestors were complex and full of unexpected twists. Abraham's story wasn't just about faith and covenant; it was also about family, legacy, and the challenges of navigating a world filled with diverse beliefs and destinies. It's a reminder that sometimes, the greatest blessings come after the hardest goodbyes.
