לְבַעֲב֤וּר סַבֵּב֙ אֶת־פְּנֵ֣י הַדָּבָ֔ר עָשָׂ֛ה עַבְדְּךָ֥ יוֹאָ֖ב אֶת־הַדָּבָ֣ר הַזֶּ֑ה וַאדֹנִ֣י חָכָ֗ם כְּחָכְמַת֙ מַלְאַ֣ךְ הָאֱלֹהִ֔ים לָדַ֖עַת אֶֽת־כָּל־אֲשֶׁ֥ר בָּאָֽרֶץ׃ (ס)
你的僕人約押這樣做,是要用迂迴的方式把這件事引到正題上。我主有智慧,如同上帝天使的智慧,能知道地上的一切事。»

ויאמר יעקב...כי על כן ראיתי, this is precisely why it is appropriate that you accept my gift for I give it to you wholeheartedly. When I looked at your face I recognised that it bears the same features as the angel whom I have encountered and who has blessed me. Yaakov alluded to that nocturnal encounter in order to make Esau afraid to harm him. Yaakov had learned from the effect an encounter with angel- albeit it in a nocturnal vision- had had upon Lavan, who had not dared to attack him (29.31) Esau was well aware that Yaakov was a righteous man ever since his youth and he did not hesitate to believe him when told that Yaakov had encounters with angels. When Yaakov flattered Esau that the latter’s features reminded him of the features of the angel he had had a dialogue with, this was an exaggeration, of course. We find a similar exaggeration in Samuel II 14,20 where the woman from Tekoah says to King David that “my lord is wise as an angel of G’d and he knows all that goes on in the land.”

on account of [literally: “in rolling over”] i.e., “for the reason of” [literally: “in turning over”]. Compare “to turn this matter the other way” [II Samuel 14: 20]. The reason behind this verse’s assertion is that all of our individual bodies are nothing more than parts of an integrated Whole.
