Shortly after the war, God revealed Himself unto Abraham, to soothe his conscience as to the spilling of innocent blood, for it was a scruple that gave him much anguish of spirit. God assured him at the same time that He would cause pious men to arise among his descendants, who, like himself, would be a shield unto their generation. As a further distinction, God gave him leave to ask what he would have, rare grace accorded to none beside, except Jacob, Solomon, Ahaz, and the Messiah.
Abraham spoke, and said: "O Lord of the world, if in time to come my descendants should provoke Thy wrath, it were better I remained childless. Lot, for the sake of whom I journeyed as far as Damascus, where God was my protection, would be well pleased to be my heir. Moreover, I have read in the stars, 'Abraham, thou wilt beget no children.' " Thereupon God raised Abraham above the vault of the skies, and He said, "Thou art a prophet, not an astrologer!"
Now Abraham demanded no sign that he would be blessed with offspring. Without losing another word, he believed in the Lord, and he was rewarded for his simple faith by a share in this world and a share in the world to come as well, and, besides, the redemption of Israel from the exile will take place as a recompense for his firm trust.
