Rebekah first saw Isaac as he was coming from the way of Beer-lahai-roi, the dwelling-place of Hagar, whither he had gone after the death of his mother, for the purpose of reuniting his father with Hagar, or, as she is also called, Keturah.
Hagar bore him six sons, who, however, did scant honor to their father, for they all were idolaters. Abraham, therefore, during his own lifetime, sent them away from the presence of Isaac, that they might not be singed by Isaac's flame, and gave them the instruction to journey eastward as far as possible. There he built a city for them, surrounded by an iron wall, so high that the sun could not shine into the city. But Abraham provided them with huge gems and pearls, their lustre more brilliant than the light of the sun, which will be used in the Messianic time when "the moon shall be confounded and the sun ashamed." Also Abraham taught them the black art, wherewith they held sway over demons and spirits. It is from this city in the east that Laban, Balaam, and Balaam's father Beor derived their sorceries.
Epher, one of the grandsons of Abraham and Keturah, invaded Lybia with an armed force, and took possession of the country. From this Epher the whole land of Africa has its name. Aram is also a country made habitable by a kinsman of Abraham. In his old age Terah contracted a new marriage with Pelilah, and from this union sprang a son Zoba, who was the father in turn of three sons. The oldest of these, Aram, was exceedingly rich and powerful, and the old home in Haran sufficed not for him and his kinsmen, the sons of Nahor, the brother of Abraham. Aram and his brethren and all that belonged to him therefore departed from Haran, and they settled in a vale, and they built themselves a city there which they called Aram-Zoba, to perpetuate the name of the father and his first-born son. 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. The descendants of Kesed, another nephew of Abraham, a son of his brother Nahor, established themselves opposite to Shinar, where they founded the city of Kesed, the city whence the Chaldees are called Kasdim.
Though Abraham knew full well that Isaac deserved his paternal blessing beyond all his sons, yet he withheld it from him, that no hostile feelings be aroused among his descendants. He spake, and said: "I am but flesh and blood, here to-day, to-morrow in the grave. What I was able to do for my children I have done. Henceforth let come what God desires to do in His world," and it happened that immediately after the death of Abraham God Himself appeared unto Isaac, and gave him His blessing.
