The ass that Balaam took with him had been created on the sixth day of the creation. He had received it as a gift from Jacob, that he might not give evil counsel to Pharaoh concerning Jacob's children. It was upon his advice, nevertheless, that Pharaoh forced the Israelites to make bricks. He took his two sons, Jannes and Jambres, for it behooves a noble man always to have at least two companions upon any journey that he undertakes.
Although God had now granted him permission to go on the journey, still His wrath was kindled when he set out. God said, "Behold, this man! He knows that I read each man's heart, and knows also that he departeth only to curse Israel." This wickedness on his part had the result that even the Angel of Mercy turned against him as an enemy, standing in his way. At first the ass alone perceived the angel, and not Balaam, for God has so arranged it that human beings may not perceive the angels that surround them or else they would through terror lose their reason. The ass, on the other hand, instantly perceived the angel. He at first stood in her way as she was in the middle of the road, so that she could turn aside on both sides; then she perceived him when the road narrowed, and she could turn to one side only; and finally she reached a spot where there was no road at all to which she could turn either on this side or on that. This was to teach Balaam the following lesson: if he wished to curse Abraham's children, he should have leeway on both sides, Ishmael's children and Keturah's children; if he wanted to curse Isaac's children, one side would still be open to him, Esau's children; but if he wanted to curse Jacob's children, he should never bring it to pass, for they are protected on both sides, on the one hand by Abraham and Isaac, on the other by Jacob and Levi, while God watches over them from above. "The wall on this side, and on that side," through which place he had to pass, were furthermore to indicate to him that he could not become master over Israel, who have in their possession the tables of the law, "that were written on both their sides." When the ass reached the wall that Jacob and Laban had erected as a token that they "would never pass over it for harm," she thrust her feet against it, to punish him for having broken his agreement with Jacob.
