First Nephi 21:1
Nephi said that he would "liken the scriptures" as he taught his brothers, certainly as he taught the whole company. By now they were half a world away from their homes in Jerusalem. He must have paid close attention to this verse from Isaiah, and felt it was speaking particularly to them, for they were "broken off and are driven out" and "scattered abroad". Yet they were still the Lord's people, still of the House of Israel. It is amazing that they had Isaiah's words and that Isaiah knew that many would be scattered. Many were scattered and we have no record of them. How fortunate we are to have the record of one of those groups.
Interestingly, the verse also speaks of the isles, and Nephi's brother Jacob thought they were upon an isle of the sea. (Second Nephi 10:20)
