Though Abraham knew full well that Isaac deserved his paternal blessing beyond all his sons, yet he withheld it from him, that no hostile feelings be aroused among his descendants. He spake, and said: "I am but flesh and blood, here to-day, to-morrow in the grave. What I was able to do for my children I have done. Henceforth let come what God desires to do in His world," and it happened that immediately after the death of Abraham God Himself appeared unto Isaac, and gave him His blessing.[316] A HERALD OF DEATH When the day of the death of Abraham drew near, the Lord said to Michael, "Arise and go to Abraham and say to him, Thou shalt depart from life!" so that he might set his house in order before he died. And Michael went and came to Abraham and found him sitting before his oxen for ploughing. Abraham, seeing Michael, but not knowing who he was, saluted him and said to him, "Sit down a little while, and I will order a beast to be brought, and we will go to my house, that thou mayest rest with me, for it is toward evening, and arise in the morning and go whithersoever thou wilt." And Abraham called one of his servants, and said to him: "Go and bring me a beast, that the stranger may sit upon it, for he is wearied with his journey." But Michael said, "I abstain from ever sitting upon any fourfooted beast, let us walk therefore, till we reach the house." On their way to the house they passed a huge tree, and Abraham heard a voice from its branches, singing, "Holy art thou, because thou hast kept the purpose for which thou wast sent." Abraham hid the mystery in his heart, thinking that the stranger did not hear it. Arrived at his house, he ordered the servants to prepare a meal, and while they were busy with their work, he called his son Isaac, and said to him, "Arise and put water in the vessel, that we may wash the feet of the stranger." And he brought it as he was commanded, and Abraham said, "I perceive that in this basin I shall never again wash the feet of any man coming to us as a guest." Hearing this, Isaac began to weep, and Abraham, seeing his son weep, also wept, and Michael, seeing them weep, wept also, and the tears of Michael fell into the water, and became precious stones.
