Why is this, that you ask my name?
In Vayishlakh, this week’s parashah, Yaaqov Avinu battles an angel. At the end he asks the angel what his name was. The angel answers, “לָמָּה זֶּה תִּשְׁאַל לִשְׁמִי — why is this that you ask my name?” A mal’akh is literally a messenger. An angel is defined by its mission. Thus the name of the angel of healing is simply “Refa’el — G-d Heals”, as one example. But the story in our parashah goes to its conclusion apparently without Yaaqov getting an answer to his question.
I would like to suggest that the angel did answer Yaaqov.
Rav Chiya bar Chanina (Bereishis Rabba #72) identifies this angel as שרו של עשו, the national angel of Eisav’s descendants. Among those descendants is Amaleiq and his offspring. Which, in turn, is a nation Rashi (Devarim 25:18) and others attribute an ideology of מקרה, it’s all happenstance. No Divine Plan or purpose to creation.
Putting those two together… When Yaaqov asks for a name, the angel replies with its name. The name is “לָמָּה זֶּה תִּשְׁאַל לִשְׁמִי — why is this that you ask my name?” The angel that is the metaphysical manifestation of Esav’s nations is the one with the function of “why ask for names?” Why are you looking for a plan or function?
