Musar su Salmi 68:14

As to the eagle, the crown and the image of the dove in the parable related by the Tikkunei Ha-Zohar: This is an allusion to the close relationship between G–d and our people. He is fond of us, and we are fond of Him. This sentiment is clearly expressed in 26,17: את ה' האמרת היום להיות לך לאלוקים וללכת בדרכיו … וה' האמירך היום להיות לו לעם סגולה… "You have affirmed the Lord this day to be your G–d and to walk in His ways,….and the Lord has affirmed you this day to be His own treasured nation…" The eagle symbolizes His fondness of us, as we know from Exodus 19,4 where G–d recalled how He transported us (the whole Jewish nation) (as) on the wings of eagles." The dove symbolizes our own fondness for G–d and our cleaving to Him to the point of preparedness to die for the sake of His Holy Name. Israel is called יונה, dove, as per Psalms 68,14: יונה נחפה בכסף, "wings of the dove covered with silver." Our sages comment on this that it is characteristic of the dove that once it has mated it will not mate with any other female. Our sages also stated (Midrash Tehillim ibid.) that the dove does not go into convulsions when it is slaughtered, just as the people of Israel do not have spasms when dying a martyr's death but accept such a death gracefully.
