Genesis 32:6

And the messengers returned to Jacob, saying, We came to thy brother Esau, and also he cometh to meet thee, and four hundred men with him. The return of Jacob's messengers without a friendly greeting was intended by Esau to make an ominous impression. As a princely sheik of the desert he came with his retainers, his sons, his servants, and other adherents, with whose aid he was gradually driving out the Horites from the land of Seir. If nothing else, Esau wanted to have his brother feel his superior power, for this he valued more highly than the promise of a religious dominion in the dim and distant future.
