Midrash sobre I Reyes 4:3

R. Jochanan said: "The feet of the man are security for him; that where he is needed, thither they will bring him." Two Ethiopians named Elihoreph and Aehiyah, the sons of Shisha, were in the service of king Solomon as scribes. One day Solomon saw that the Angel of Death was sad, and he asked him for the reason; and he said: "Because the two men are required by me." Solomon took the two men and gave them away to the demons with instructions to carry them off to the city of Luz. When they reached the gates of Luz, the two men died. On the morrow, he saw the Angel of Death very cheerful; and when he asked him the reason, the Angel replied: "To the place where I was commanded to take the lives of these two men thou hast sent them." Then remarked Solomon: "The feet of a man are his security; where he is needed, to that place they bring him."
