Rabbi Hizkiyah opened, “It is written, as a rose among thorns.” (Song of Songs 2:2) What is the Rose? It is the Congregation of Israel. Because there is a rose, and there is a Rose. Just as the rose among the thorns is tinged with red and white, so is the Congregation of Israel affected by the qualities of Judgment and Mercy. Just as a rose has thirteen petals, the Assembly of Israel is surrounded on all sides by the thirteen attributes of Mercy. Thus, between the first mentions of the name Elohim, [in the Torah] these [thirteen] words surround and guard the Congregation of Israel.
