“My rainbow I have placed in the cloud, and it shall be for a sign of a covenant between Myself and the earth.” - Genesis 9:13
“The rainbow is the symbol of a world safe for diversity - many colours, one light.” - Lord Rabbi Jonathan Sacks.
This week’s Parasha, “Noach,” focuses on The Flood which G-d brings upon humanity for its pernicious conduct, His decision to salvage Noach drives Him to enter a covenant with him and all living creatures culminating with the promise to never again destroy the world by water. This act, suggests Lord Rabbi Sacks, is when “morality was born.”
The sign of the Noachide Covenant, as the verse above mentions, is the “Rainbow in the Cloud."
The rainbow, as many of us know, is not the result of any wonderous miracle but rather a natural phenomenon with a simple scientific explanation. Science tells us that a rainbow is the result of the burst of the sun rays against the raindrops.
However, in this Parashah, the choice of the image of the rainbow carries a deep symbolic moral and theological meaning and has been the topic of interpretation by many of our Jewish sages.
Rash”i, for instance, explains that the rainbow is a reminder of Divine Mercy. Whenever the world’s sins might justify destruction, G-d “sees the bow” and remembers His promise not to destroy humanity.
Ramba”n (Nachmanides) notes that the bow, symbolizing G-d’s weapon, points upward, curving away from the earth.
Midrash Rabba (Beresheet Rabbah 35:3), likewise, interprets the rainbow as a bow of Peace. Just as the warrior hangs up his weapon, G-d has “hung” His bow in the sky.” It serves as a gesture of reconciliation.
The Talmud, in Chagigah 16a, proposes that seeing the rainbow is a serious spiritual moment where one is expected to recite the following blessing, “Blessed are You, Lord our G-d, King of the universe who remembers the covenant, and is faithful to His covenant, and keeps His promise.”
The covenant of the rainbow, as mentioned above, is not limited to the Jewish People but extends to “every living creature.” Its universality is what prompts Lord Rabbi Sacks to focus his beautiful interpretation on the symbolism embedded in the rainbow's many colours.
For Sacks, the rainbow's spectrum of colours symbolizes unity in diversity. Each colour, he notes, is distinct, yet together, they form one congenial whole. Just as the colours remain distinct yet form one harmonious arc, humanity too is meant to preserve difference within unity.
May the light of the Noachide rainbow, the sign of the covenant that celebrates moral responsibility and human diversity continue to shine upon us and be a constant reminder that even after the storm and after judgement, there is Hope, Renewal and a prospect for Peace.
Shabbat Shalom, fellow Jews and every blessing to all
