The servants of Jacob went before him with the present for Esau, and he followed with his wives and his children. As he was about to pass over the ford of Jabbok, he observed a shepherd, who likewise had sheep and camels. The stranger approached Jacob and proposed that they should ford the stream together, and help each other move their cattle over, and Jacob assented, on the condition that his possessions should be put across first. In the twinkling of an eye Jacob's sheep were transferred to the other side of the stream by the shepherd. Then the flocks of the shepherd were to be moved by Jacob, but no matter how many he took over to the opposite bank, always there remained some on the hither shore. There was no end to the cattle, though Jacob labored all the night through. At last he lost patience, and he fell upon the shepherd and caught him by the throat, crying out, "O thou wizard, thou wizard, at night no enchantment succeeds!" The angel thought, "Very well, let him know once for all with whom he has had dealings," and with his finger he touched the earth, whence fire burst forth. But Jacob said, "What! thou thinkest thus to affright me, who am made wholly of fire?"[247] The shepherd was no less a personage than the archangel Michael, and in his combat with Jacob he was assisted by the whole host of angels under his command. He was on the point of inflicting a dangerous wound upon Jacob, when God appeared, and all the angels, even Michael himself, felt their strength ooze away. Seeing that he could not prevail against Jacob, the archangel touched the hollow of his thigh, and injured him, and God rebuked him, saying, "Dost thou act as is seemly, when thou causest a blemish in My priest Jacob?" Michael said in astonishment, "Why, it is I who am Thy priest!" But God said, "Thou art My priest in heaven, and he is My priest on earth." Thereupon Michael summoned the archangel Raphael, saying, "My comrade, I pray thee, help me out of my distress, for thou art charged with the healing of all disease," and Raphael cured Jacob of the injury Michael had inflicted. The Lord continued to reproach Michael, saying, "Why didst thou do harm unto My first-born son?" and the archangel answered, "I did it only to glorify Thee," and then God appointed Michael as the guardian angel of Jacob and his seed unto the end of all generations, with these words: "Thou art a fire, and so is Jacob a fire; thou art the head of the angels, and he is the head of the nations; thou art supreme over all the angels, and he is supreme over all the peoples. Therefore he who is supreme over all the angels shall be appointed unto him who is supreme over all the peoples, that he may entreat mercy for him from the Supreme One over all." Then Michael said unto Jacob, "How is it possible that thou who couldst prevail against me, the most distinguished of the angels, art afraid of Esau?"
