Here, the one who examines the Song of the Sea will notice that there are three points within it that relate to and deal with the future:

1. The first point is the verse "Until Your people, Hashem, pass by, until this people You have acquired pass by" (Exodus 15:16). About this, the sages (Sotah 36a) have said, and this is their language: 'Until Your people, Hashem, pass by' – this is the first coming. 'Until this people You have acquired pass by' – this is the second coming. From this, say that the Israelites were worthy of having a miracle performed for them at the second coming as at the first, but sin caused otherwise. Their words end here. This means that the reason for the repetition of 'pass by' in the verse – 'Until Your people pass by' and again 'until this people pass by' – is because the Israelites came to the Land of Israel twice. The first time, when they left Egypt after wandering in the desert for forty years. And the second time, when they returned from the Babylonian exile led by Ezra the Scribe, during the building of the Second Temple. And from the comparison of these two comings, the Gemara learned that the Israelites were worthy of having a miracle performed for them, etc. In any case, here we have one point where the Song of the Sea deals with the future to come.

2. The second point: in the following verse, "You will bring them and plant them on the mountain of Your inheritance." Rashi explained: "You will bring them" – Moses prophesied that he would not enter the land, and therefore it does not say 'You will bring us.'"

3. The third point, in the same verse: "The place You made for Your dwelling, Hashem, the sanctuary, O Lord, Your hands established." Rashi explained that this is a prophecy about the Third Temple that will be built quickly in our days. This is his language: "Beloved is the Temple, for the world was created with one hand, as it says (Isaiah 48:13), 'My own hand founded the earth,' but the Temple with two hands. And when will it be built with two hands? When Hashem will reign forever and ever, in the future when all dominion is His." End of his words. Here we have three places where this song deals with future events that have not yet occurred.

At first glance, this is a wonder, for the essence of the song is thanksgiving, and how is it possible to sing and give thanks for an event that has not yet happened? In a straightforward explanation, we can say that these verses, although they are fixed in the Song of the Sea and were even said with it on the shore of the sea, are not of the essence of the song but are words of prayer and request that were integrated and inserted into it. Like what the Ramban wrote in explaining the statement (Exodus 15:18) "Hashem will reign forever and ever," that it is a matter of prayer: "It means that He has now shown that He is king and ruler over everything, having saved His servants and destroyed His rebels. So may it be His will to do in all generations forever, not to withdraw His eye from the righteous and not to hide it from the wicked who do evil." And we will further discuss this verse in detail below.
