Kabbalah su Genesi 32:7

"And the messengers returned to Jacob, saying: 'We came to your brother Esau, and he is also coming to meet you, and four hundred men with him'" (Beresheet 32:7). He asks, After saying, "We came to your brother," do we not know they referred to Esau, as he had no other brothers? He answers, "We came to your brother" means that he did not repent and walk the path of righteousness, as may be thought, but remained the evil Esau as before. "and he is also coming to meet you..." does not mean, as you may say, by himself, but rather he has "four hundred men with him."
