As they sat and ate, Abraham said, “Thou knowest well, dear wife, that I knew the one true God from the time that I was three years old. Isaac is older, and it behoves him to know more of the law of God. Therefore I design to take him with me to Shem and Eber, our ancestors, who live not far from here, that they may instruct him. Hast thou any thing to object to this, Sarah?” She answered, “No; do that which is pleasing in thine eyes; only let not Isaac be away too long, for thou knowest how precious the sight of him is to me.” Then Sarah put her arms round her son, and kissed him, and they parted with many tears; and she exhorted Abraham to have great care of the youth, that the journey might not be too great for him. Next morning, very early, Abraham rose, and he saddled the ass himself, though he had many slaves, for he was eager to be gone, and to go where the Lord called him. This was the ass, born of the she-ass created by God on the eve of the sixth day, upon which Moses afterwards rode when he went to Egypt:[327] it is the ass which spake to Balaam, and it is the ass of which the prophet Zechariah has spoken, that on it Messiah shall ride.[328] This ass was of a hundred colors.[329] Sarah clothed Isaac in the garment that Abimelech had given her, and placed a jewel-studded fillet about his head. She provided the travellers with food for their journey, and accompanied them with her maids, till Abraham bade them return. Then she clasped Isaac once more to her breast, and said with tears, “God be gracious to thee, my son; how know I that I shall see thee again?” Abraham had two to accompany him, Eliezer and Ishmael; he had cut fig and palm wood and made a fagot. On the way this discourse took place between Eliezer and Ishmael. Ishmael said, “I perceive clearly that my father is about to offer Isaac as a whole burnt offering; therefore I, his eldest son, will inherit his possessions.” But Eliezer said, “That is false: I am his trusty servant! Did not thy father drive thee away from home? He will leave all to me.” Whilst they thus spake, there came a voice from heaven, “O ye fools! neither of you knows the truth.” Abraham in the mean time walked forward. Then came Satan to him in the form of an old man bowed upon a staff, and said to him, “Whither goest thou?” He answered, “I go to offer up my prayers.” “Wherefore this knife, and fuel, and fire?” asked Satan. “I take them in case we have to spend much time on the mountain, that we may bake bread and slay beasts.”
