Zitat Kommentar zu Schemuel I 17:21

The tav in you drank denotes the second person masculine singular. It suggests a man speaking to his fellow, saying, “there is so much abundance, you will drink wine constantly”. There are those, however, who say that the tav denotes the third person feminine singular, and that grape acts as the feminine subject of the verb. This suggestion is vacuous, though, because it would require the tav to be vocalized with a pattaḥ, in the form of a causative hif‘il verb. A slightly more plausible reading is suggested by those who say that the feminine subject of the non-causative verb is the implied word “congregation”, since the congregation of Israel is sometimes masculine and sometimes feminine [e.g., I Samuel 17: 21].

כי אם יהיה לבער קין עד מה אשור תשבך, “yet shall Kayin be consumed when Ashur takes you captive.” According to Ibn Ezra, Bileam uses the word Kayin to describe the Kenite, saying: “how long can Ashur keep you captive, i.e. the exile of the Ten Tribes of the Jewish people by the Assyrians is of limited duration, whereas the other captives of Assyria would never regain their freedom. The reason the word Assyria is used in the feminine gender is that Bileam relates to the camp of Assyria, similar to Job 1,15 referring to Sheba in the feminine gender. The same feminine form is used to describe Israel in verse Samuel I 17,21.
