Though Abimelech had done him great injury, Abraham not only granted him the forgiveness he craved, but also he prayed for him to God. Thus he is an exemplar unto all. "Man should be pliant as a reed, not hard like the cedar." He should be easily appeased, and slow to anger, and as soon as he who has sinned against him asks for pardon, he should forgive him with all his heart. Even if deep and serious injury has been done to him, he should not be vengeful, nor bear his brother a grudge in his heart.[199] Abraham prayed thus for Abimelech: "O Lord of the world! Thou hast created man that he may increase and propagate his kind. Grant that Abimelech and his house may multiply and increase!"[200] God fulfilled Abraham's petition in behalf of Abimelech and his people, and it was the first time it happened in the history of mankind that God fulfilled the prayer of one human being for the benefit of another.[201] Abimelech and his subjects were healed of all their diseases, and so efficacious was the prayer offered by Abraham that the wife of Abimelech, barren hitherto, bore a child.[202] THE BIRTH OF ISAAC When the prayer of Abraham for Abimelech was heard, and the king of the Philistines recovered, the angels raised a loud cry, and spoke to God thus: "O Lord of the world! All these years hath Sarah been barren, as the wife of Abimelech was. Now Abraham prayed to Thee, and the wife of Abimelech hath been granted a child. It is just and fair that Sarah should be remembered and granted a child." These words of the angels, spoken on the New Year's Day, when the fortunes of men are determined in heaven for the whole year, bore a result. Barely seven months later, on the first day of the Passover, Isaac was born. The birth of Isaac was a happy event, and not in the house of Abraham alone. The whole world rejoiced, for God remembered all barren women at the same time with Sarah. They all bore children. And all the blind were made to see, all the lame were made whole, the dumb were made to speak, and the mad were restored to reason. And a still greater miracle happened: on the day of Isaac's birth the sun shone with such splendor as had not been seen since the fall of man, and as he will shine again only in the future world.[203] To silence those who asked significantly, "Can one a hundred years old beget a son?" God commanded the angel who has charge over the embryos, to give them form and shape, that he fashion Isaac precisely according to the model of Abraham, so that all seeing Isaac might exclaim, "Abraham begot Isaac."[204]
