Musar do Hioba 1:6

"The emissaries returned to Jacob." This refers to the human as well as to the spiritual emissaries. The spiritual emissaries told Jacob: באנו אל אחיך, "We have come to your brother, whereas the human emissaries told him: אל עשו, "To Esau." He is also coming to meet you;" this was said by the emissaries sent to the Celestial Regions who reported about Samael. וגם ארבע מאות איש עמו; "and he also has four hundred men with him." This was reported by the human messengers who had been despatched to Esau.
