One version is that both Moses and Aaron ascended Hor, knowing that one of them was to die, but uncertain which, and they found a cave, and a sarcophagus therein with the inscription on it, “I am for him whom I fit.”
Moses tried to lie down in it, but his feet hung out; Aaron next entered it, lay down, and it fitted him exactly.
Then Gabriel led Moses and the sons of Aaron out of the cave, and when they were again admitted Aaron was dead.[[575]]
Another version is this: God announced to Moses that he would call Aaron to Himself. Then Moses took his brother from the camp, and they went into the desert, till they came to a tree. When Aaron saw the shadow, he said, “O my brother, whose tree is this?”
Moses said, “God alone knows.”
Then spake Aaron, “I am weary, and the shadow is cool; suffer me to repose a little while under the tree.”
Moses said, “Lie down, my brother; and may thy rest be sweet.”
Aaron lay down, and Moses sat beside him till he died.
Then suddenly the tree, the shadow, and Aaron vanished; and Moses returned alone to the Israelites. They were angry with him, that he had not brought back Aaron, and they took up stones against him. But Moses cried to the Lord, and the Lord showed them Aaron on a bed, and he was dead; and the people looked, and wondered, and wept: then said a voice from heaven, “God hath taken him.” The people bewailed him many days.[[576]]
