Vayishlach 32:4
וַיִּשְׁלַ֨ח יַעֲקֹ֤ב מַלְאָכִים֙ לְפָנָ֔יו אֶל־עֵשָׂ֖ו אָחִ֑יו אַ֥רְצָה שֵׂעִ֖יר שְׂדֵ֥ה אֱדֽוֹם And Yaakov send emissaries (angels) before him to his brother Esav, to the land of Seir, the field of Edom
At the conclusion of the previous Parsha we find that holy angels met Yaakov to accompany him and return him to his home in peace. Yaakov created a brotherhood with them as if they were human like him. He assumed that he was about to live in peace having just escaped from the terrors of Lavan, however, it still remained for him to strive with an even more challenging tyrant, his brother Esav. The angels had been sent so that Yaakov should utilize them in humbling that haughty heart of the wicked Esav, and Yaakov immediately sent them on their way to carry out his instructions like a master who instructs the members of his household with no fear.
This is what we are taught that מלאכים, while conventionally understood as emissaries, in this context is literally meant to indicate angels. Why, then, did he find it necessary to tell the all-knowing angles where to find Esav? Yaakov's plan was to utilize them to utterly destroy the minions of evil. He assumed that angels could not possibly have been sent to him to perform a minor task, he must be meant to utilize their great power for a very significant purpose. That is why he instructed them to go to ארצה שעיר שדה אדום, the land of Seir represents the masculine aspects of the forces of evil, whereas the fields of Edom represents the feminine aspects of the evil forces of impurity. He sent them there to completely rid the world of the klipah, the superficial shell of reality that is disconnected from the inner spirituality. This was a task fit for angels.
But Yaakov then had second thoughts as he was divinely inspired to realize that it was not yet the time to do untterly destroy evil. On the contrary, it was his mandate to humble himself before Esav and to allow the klipah (literally, the shell) to temporarily take precedence, just as had happened at birth (Esav was born before Yaakov), and as we find in nature that one must get past the shell before enjoying the fruit.
Vayishlach 32:5
Yaakov therefore changed his plans and instructed the angels to act deferentially before Esav. וַיְצַ֤ו אֹתָם֙ לֵאמֹ֔ר כֹּ֣ה תֹאמְר֔וּן לַֽאדֹנִ֖י לְעֵשָׂ֑ו כֹּ֤ה אָמַר֙ עַבְדְּךָ֣ יַעֲקֹ֔ב And he commanded them saying, "So shall you say to my master, to Esav, so says your servant Yaakov." He gave mastery to Esav and servitude for himself. He knew that this was what was currently needed and then anyone who tries to speed up the clock, finds the clock pushing back. A wise heart knows the time for justice.
עִם־לָבָ֣ן גַּ֔רְתִּי וָאֵחַ֖ר עַד־עָֽתָּה׃ I dwelled with Lavan and delayed until now Yaakov spoke like a servant who needs to excuse himself to his master for not completing his responsibilities in a timely manner because there were extenuating circumstance. This was Yaakov completely humbling himself as was necessary at the time.

Vayishlach 32:6
Yaakov also sent a message to Esav to inform him that he had acquired five categories of goods while he was in the house of Lavan, וַֽיְהִי־לִי֙ שׁ֣וֹר וַחֲמ֔וֹר צֹ֖אן וְעֶ֣בֶד וְשִׁפְחָ֑ה וָֽאֶשְׁלְחָה֙ לְהַגִּ֣יד לַֽאדֹנִ֔י לִמְצֹא־חֵ֖ן בְּעֵינֶֽיךָ I have oxen, donkeys, sheep, servants and maid-servants which I sending to inform my master so I find favor in his eyes. Yaakov was offering all he had to Esav to do with at his pleasure as everything that a slave has belongs to his master. He could not possibly have humbled himself more than that.
In Yaakov's words there was also something more fundamental. He wanted to let Esav know how God had watched over him, that even in a house of impurity he had not lost his holiness. עִם־לָבָ֣ן גַּ֔רְתִּי I dwelled with Lavan, the word גרתי can be rearranged to spell תרי"ג, the 613 commandments which Yaakov heeded despite very adverse circumstance. God empowered him to overcome the most difficult klipos, which are represented by the ox and donkey, and he was hoping that upon hearing this Esav would think twice about trying to harm him. There was, therefore, a superficial meaning to his message, namely that of humbling himself, and a deeper message within.
