2 Nephi 15 – 16
In this story of the vineyard Israel is not the vine, they are the land. The vine (the choisest vine) is the gospel and priesthood , it is the covenant. Although the fruits of the vine are the doings of the people. This says that the men of Judah are the plant, but I would say that it is because of the covenant of the Lord unto them, and not the men in particular. It seems to be because the people of the covenant brought forth only wild grapes that Isaiah was called to make their ears heavy with things they would not understand.
