This is the secret of "Behold, Esau my brother is a hairy (Heb. sa'ir) man" (Beresheet 27:11), AS HE IS AN ASPECT OF THE OTHER SIDE. IT CONTAINS MALE AND FEMALE CHARACTERISTICS, and just as in the side of holiness there is male and female, so too in the side of defilement there exist a male and female. A popular saying goes like this: Throw a bone to a dog and he will lick the dust off your feet; HERE ALSO, WE GIVE TO THE OTHER SIDE A GOAT AND HE IS CONVERTED TO BE A DEFENDER.

While he is dragging THE BONE, people may enter the palace of the King and no one dares to stop them, FOR THE ACCUSER IS PREOCCUPIED WITH HIS GIFT. Afterwards, he will still be wagging his tail, MEANING HE WILL BECOME A DEFENDER.
