Genesis 32:8

Gen 32:8 And said, If Esau come to the one company, and smite it, then the other company which is left shall escape.

Ver. 8. If Esau come, &c.] It is a point of prudence, if we cannot keep all, to save what we can.

And said, if Esau come to the one company, and smite it,.... The first, which perhaps consisted only of some servants, with a part of his cattle; so that if Esau should come in an hostile manner, and fall upon that, and slay the servants, and take the cattle as a booty:

then the other company which is left shall escape; by flight, in which most probably were he himself, his wives and children, and the camels to carry them off who would have notice by what should happen to the first band; but one would think, that, notwithstanding all this precaution and wise methods taken, there could be little expectation of escaping the hands of Esau, if he came out on such an ill design; for whither could they flee? or how could they hope to get out of the reach of four hundred men pursuing after them, unless it could be thought, or might be hoped, that the first company falling into his hands, and the revenge on them, and the plunder of them, would satiate him, and he would proceed no further? but Jacob did not trust to these methods he concerted, but betakes himself to God in prayer, as follows.

Either by flight, or because he supposed Esau’s revenge would be satisfied with the first slaughter.

Jacob, fearing the worst, divided his people and flocks into two camps, that if Esau smote the one, the other might escape. He then turned to the Great Helper in every time of need, and with an earnest prayer besought the God of his fathers, Abraham and Isaac, who had directed him to return, that, on the ground of the abundant mercies and truth (cf. Gen 24:27) He had shown him thus far, He would deliver him out of the hand of his brother, and from the threatening destruction, and so fulfil His promises.

ויירא...ויצר HE FEARED GREATLY AND WAS DISTRESSED — He was afraid lest he be killed, and he was distressed that he might have to kill someone (Genesis Rabbah 76:2).

THEN JACOB WAS GREATLY AFRAID. This was because they told him that Esau had gone forth from his city and was coming to meet Jacob, and moreover, that he took along many men — four hundred. He thus greatly feared for his life, for he said, “He has not taken all these men except for the purpose of waging war against me.”It appears to me in this matter that Esau did not receive the messengers properly and paid them no heed. Perhaps they did not even come before him for he did not at all give permission for them to come before him and speak to him for otherwise, Scripture would have related that Esau questioned them concerning his brother’s welfare and about his circumstances and those of his household and children. [Scripture further would have told how Esau requested] that they convey greetings to Jacob and tell him that he is proceeding towards him to see him, and they would have told it thus to Jacob. Scripture, however, does not narrate that the messengers transmitted a word in Esau’s name. Instead, he [Esau] kept his wrath in his heart, and he came with his army for the purpose of doing Jacob evil. Now the messengers had investigated the matter in the camp, and they knew that he was going to meet Jacob. This is the meaning of the word vegam (and moreover) [in the verse, and moreover he goeth to meet thee], for they said, “We came to thy brother Esau, but he did not answer us a word, and he sent you no greeting, and moreover, he goeth to meet thee with might and an army.” This was why he added fear to his fear, as Scripture says, And Jacob was greatly afraid, and was distressed. And so our Rabbis said that the messengers recognized hatred in him[Esau]. Thus they said: “We came to thy brother Esau. You behave towards him like a brother, but he behaves towards you like Esau the villain.” However, in the end, when Esau saw the great honor that Jacob bestowed upon him and how he prostrated himself before him, bowing to the ground seven times from the distance until he approached him, his mercy was aroused, and he thought that Jacob is recognizing his birthright and his pre-eminence, as I have explained. And with this he was comforted, for the hearts belong to G-d, Who turns them whither He will.

ויירא ויצר, the reason why the Torah repeated the emotions Yaakov experienced twice but in different words was to underline how strongly he felt this fear. In Bereshit Rabbah 76,2 these two expressions are described as basically meaning the same thing, the only difference being that the former is intransitive, Yaakov being afraid of being killed, whereas the latter describes a similar fear, but that of having to kill one’s adversary.

ויחץ, Rabbah Chiyah said that in this part of the verse the Torah teaches us prudence. A man must not place all his eggs in one basket.
