7. "You shall be holy: for I Hashem your Elohim am Holy" (Vayikra 19:2). Rabbi Yitzchak commenced: "O (also: 'Woe') land of buzzing wings..." (Yeshayah 18:1). HE QUESTIONS: Just because it is a land of buzzing wings, is that such a cause for alarm that the verse writes, "Woe land?" HE ANSWERS: As Rabbi Yitzchak explained, at the time the Holy One, blessed be He, created the world and wanted to reveal matters of depth from among concealed matters, and light from darkness, these terms were intermingled. For this reason, from darkness came light, and concealment departed and became known as the depth. And this resulted from it. So from good came evil, from Mercy came Judgment. All intermingled, the Good Inclination with the Evil one, right and left, Yisrael and other nations, white and black. Each thing was dependent on the other.
