“And Jacob sent messengers.”
– Genesis 32:4, JPS 1917 Tanach
“This parasha was written to show how H’Shem saved his servant from a stronger foe, and sent his angels to rescue him. In addition, it teaches us that he [Jacob] didn’t rely on his righteousness, and made every effort to save himself.” – Ramban, sefaria.org
Previously, the Torah speaks of two camps of angels, one that accompanied Jacob to the edge of the land of Canaan, and another camp that served to accompany him and his entourage once they entered Canaan, the land promised to Abraham, Isaac, and Jacob, and their descendants (see Genesis 32: 2-3). Now, at the beginning of parashas Vayishlach, the Torah, seemingly so, alludes to these angels that were assigned for protective measures (Genesis 32:4).
“Jacob sent messengers [malachim] before him to Esau his brother unto the land of Seir, the field of Edom” (Genesis 32:4, JPS). The Hebrew word, malachim can mean messengers or angels. In the literal sense, Jacob sent messengers to Esau; yet, on another level, the angels granted to him for protection may have also gone ahead of Jacob’s entourage.
Regardless of the interpretation, if Jacob had the opportunity to seek divine protection from angels who would actually defend his entourage, he did not rely on this; rather, he made a three-fold preparation for an encounter with Esau: prayers, appeasement, and a defensive strategy. He prayed to H’ Shem for deliverance from the hands of Esau; sent gifts to Esau to appease his resentment; and he divided the camp, so that if one camp was attacked, the other would have the opportunity to escape. Although Jacob could have prevailed upon H’Shem to rescue him through an angelic force, he chose humility, by subjecting himself in all deference to his brother, Esau.
