Kabbalah su Isaia 10:21

Rabbi Chiya said from here, as it is written, "A remnant shall return, even the remnant of Jacob" (Isaiah 10:21). About these remaining blessings, it is also written, "And the remnant of Jacob shall be in the midst of many peoples" (Michah 5:6), among all the nations, not Esau alone, as it is written, "And the remnant...like dew from Hashem."
