But all these Divine blessings showered upon Abraham were not undeserved. He was clean of hand, and pure of heart, one that did not lift up his soul unto vanity.
He fulfilled all the commands that were revealed later, even the Rabbinical injunctions, as, for instance, the one relating to the limits of a Sabbath day's journey, wherefor his reward was that God disclosed to him the new teachings which He expounded daily in the heavenly academy.
But one thing lacked to complete the happiness of Abraham, the marriage of Isaac. He therefore called his old servant Eliezer unto himself. Eliezer resembled his master not only externally, in his appearance, but also spiritually. Like Abraham he possessed full power over the evil inclination, and like the master, the servant was an adept in the law. Abraham spake the following words to Eliezer: "I am stricken in age, and I know not the day of my death. Therefore prepare thyself, and go unto my country, and to my kindred, and fetch hither a wife for my son." Thus he spake by reason of the resolution he had taken immediately after the sacrifice of Isaac on Moriah, for he had there said within himself, that if the sacrifice had been executed, Isaac would have gone hence childless. He was even ready to choose a wife for his son from among the daughters of his three friends, Aner, Eshcol, and Mamre, because he knew them to be pious, and he did not attach much importance to aristocratic stock. Then spake God to him, and said: "Concern thyself not about a wife for Isaac. One has already been provided for him," and it was made known to Abraham that Milcah, the wife of his brother Nahor, childless until the birth of Isaac, had then been remembered by God and made fruitful. She bore Bethuel, and he in turn, at the time of Isaac's sacrifice, begot the daughter destined to be the wife of Isaac.
