הַאֲזִינוּ - Haazinu

1st Aliyah

The heavens and earth, permanent fixtures of this world, are called upon to be witnesses to the words which Moses will now say. The Torah, Moses declares, is life to this world, much as rain and dew are to vegetation. G‑d is righteous and just, and all corruption stems from His children, who are thankless and lack the wisdom to recognize the source of all their blessing.

2nd Aliyah

Moses beseeches the Israelites to contemplate their history, starting with the generation of the Tower of Babylon. When that generation sinned, G‑d could have destroyed humanity, but instead chose to spare them, only because of Israel — G‑d's portion — which was destined to arise from those people. In the desert, in a "desolate, howling wasteland," G‑d enveloped and protected the Israelites with clouds, caring for His nation as an eagle tenderly cares for his offspring, treating them like the pupil of His eye. "G‑d alone guided them, and no other god was able to disturb them."
