The Rock

הצור תמים פעלו כי כל דרכיו משפט
The Rock, His work is perfect; for all His ways are justice (32:4).

Throughout his song, Moses refers to G-d as The Rock, הצור which recalls the pivotal episode of Moses striking the rock in Numbers (20:11). At the end of Parsha Haazinu, we see that Moses accepts his fate of not entering the Land of Israel and does not argue with G-d when He tells him that the time has come for him to die and that he will not enter the Land.

We read Parsha Haazinu on Shabbat (Shuva שבת שובה) (Shabbat of Return), which is the last Sabbath before יום הכיפורים (Yom Kippur) and the last Sabbath to return to G-d before the Judgement Day. On this Sabbath, it is clear that the heavens are always listening to us and accepting of us should we choose to repent, as G-d said:

Return to me and I will return to you, says the L-rd of Hosts (Zechariah1:3).

Also, some understand the word השנה (the year) of ראש השנה or Rosh Hashanah to come from the word שינוי or change. On Rosh Hashana, we have to reevaluate our lives and try to change for the better.
