Rabbi Shimon explains to Rabbi Aba that the angel prevailed over Jacob at night because he was from the side of judgment and night, but when daylight came his power was lessened and Jacob was able to overpower him. Jacob worried lest the angel should hold his usurpation of Esau's blessings against him, but the angel acknowledged that he had acquired the blessings rightfully, and he renamed Jacob Israel. Rabbi Shimon says that if the desire of Malchut is aroused first, drawing God to her with love and desire, she is filled from the right side, that is considered male, and she bears a boy child. God therefore decrees whether a boy or a girl shall be conceived. Desire should be prevalent first in the world, since in every sense people should desire God.
