In Hebrew the term branch often symbolized the Messiah (see Jeremiah 23:5–6). It can also refer to righteous groups of the house of Israel who have been cleansed and redeemed (see Isaiah 60:21; 2 Nephi 3:5; 10:1; Jacob 2:25).
“Escaped of Israel” (2 Nephi 14:2) refers to members of the house of Israel who, through personal righteousness, escaped the judgments that came upon the wicked.
