Pareshat Haazinu is always  read in the beginning of the year, either before or after Yom Kippur,  at a time when we feel close to the Al-mighty.  The Commentators note  several references to the High Holiday season in the Paresha  and I would like to share with you one of them. 
The song of Haazinu describes the journey of humanity and the Jewish people.
When expressing the kindness of Hashem to the children of Israel in the wilderness the verse states: "He found them in a desert land, and in the waste howling wilderness; he surrounded them, he instructed them, he protected them like the Ishon of his eye." Rashi, in his commentary to the Torah, explains the word Ishon as the blackness of the eye- the pupil. According to this reading Hashem protects the children of Israel with great sensitivity just as one protects his pupil. Rabbi Shmuel ben Meir, the grandson of Rashi, has a different understanding of the word Ishon. Rabbi Shmuel ben Meir understands the word Ishon to be the “flesh that is drawn down over the eye” namely, the eyelid. In biblical Hebrew Ishon means darkness thus the eyelid is an Ishon because it makes things dark. According to Rabbi Shmuel ben Meir the verse is telling us that Hashem protected the children of Israel in the wilderness just as the eyelid protects the eye.
Rabbi Shmuel ben Meir identifies  Hashem’s protection of the Jewish people as that of an eyelid.  To  better appreciate what the Al-mighty is doing for the sake of the children  of Israel, we must understand the significant role of the eyelid and  blinking.  Blinking automatically supplies moisture to our eyes to keep  them from drying out.  In addition, it keeps foreign matter from entering  and irritating our eyes.  Accordingly, Hashem, metaphorically, gives  these services to the Jewish people.  
Every year during the special  period of Aseret Yemei Teshuva, Hashem, by being close to every  single Jew, provides an opportunity for the Jew to revitalize his spiritual  health and avoid a spiritual dry-out.  In addition, it is a time to  remove the impurities of sin through Teshuva.  The two functions  of the eyelid and blinking come to life during this wonderful period,  and therefore the song of Haazinu, that describes Hashem as the  eyelid, is appropriate for this time.
