זַמְּר֣וּ אֱלֹהִ֣ים זַמֵּ֑רוּ זַמְּר֖וּ לְמַלְכֵּ֣נוּ זַמֵּֽרוּ׃
זינגט צו גאָט, זינגט, זינגט צו אונדזער מלך, זינגט.
Rabbeinu Bahya
עזי וזמרת י-ה, “G’d’s might and vengeance was my salvation.” When Moses referred to G’d by the term עזי, he paraphrased what is written in Psalms 68,29: צוך אלו-היך עזך, “your G’d has ordained might for you.” The words זמרת י-ה are related to Samuel II 23,1 ונעים זמירות ישראל, “the favorite of the songs of Israel.” This term also occurs in Psalms, 47,7 זמרו לאלו-הים זמרו, “Sing, O sing to G’d; O sing.”
ויהי לי לישועה, “G’d became my salvation.” The reason the redemption from Egypt is always referred to as ישועה, is because it was followed by another exile. The redemption of the future which will not be followed by another exile, will become known as ישועות, (plural). This is why we have David (Psalms 53,7) express his hope for מי יתן מציון ישועות ישראל, “O that the deliverance of Israel might come from Zion!” On another occasion the final redemption is called תשועת עולמים, in Isaiah 45,17: ישראל נושע בה' תשועת עולמים, “But Israel has won through the Lord triumph everlasting.” In a parallel sense the “song” Moses sang at the Sea of Reeds is known as שירה, “a song (feminine),” whereas the song that will be sung after the final redemption will be known as שיר, “a song (masculine),” reflecting the permanent nature of that redemption; compare Isaiah 26,1 ביום ההוא יושר השיר הזה,”On that day this song which will be sung will be masculine.”
