This week we read Parashat Haazinu. Although it is not the last parasha of the Torah, it is the last one we read during a Shabbat, because the Torah’s very last one, Vezot Habracha, is only read during the festival of Simchat Torah.
Most of Haazinu is a poem that Moses said before he died. The poem opens with the following words, “Listen, O heavens, and I will speak! And let the earth hear the words of my mouth!” (Deuteronomy 32:1).
Why did Moses choose the heavens and the earth as the witnesses for his words? According to Rashi, who follows the Midrash Sifrei, Moses was afraid of picking human witnesses. He thought, “I am made of blood and flesh, tomorrow I can die. If the people Israel comes tomorrow and says – We have never accepted the covenant” – who will be able to oppose them? Therefore, Moses had the heavens and the earth as witnesses, because they are eternal witnesses.
