Ha’azinu is read on the Shabbat after Yom Kippur. The first six aliyot are the Song of Ha’azinu, which starts with Moshe calling on heaven and earth to witness the warning that the nation will rebel after entering the Land of Israel, forsaking devotion to God for the pursuit of material possessions. This will lead to terrible consequences. Ha’azinu would then be read to the people, to remind them of the cause of their woes. The Song ends with God’s promise to avenge those nations who would attack the Jews. In the seventh aliyah, God tells Moshe to view the Land from the mountains of Moab and reminds him that he will not enter the Land because he hit the rock (see Bemidbar 20:12-13).
