Exodus 15:1

אָז יָשִׁיר מֹשֶׁה וּבְנֵי יִשְׂרָאֵל אֶת הַשִּׁירָה הַזֹּאת לַָה’ וַיֹּאמְרוּ לֵאמֹר אָשִׁירָה לַה’ כִּי גָאֹה גָּאָה סוּס וְרֹכְבוֹ רָמָה בַיָּם

Then Moses and the children of Israel sang this song to G-d, saying, “I will sing unto G-d because He is highly exalted; the horse and its rider He has thrown into the sea.”

The word “yashir” is rendered as “sang,” but it literally means “will sing.” Rashi cites the Talmud (Sanhedrin 91b) that this verse is an allusion to the future revival of the dead. Not only did Moshe lead the celebration to G-d at the sea, he will do so again in Messianic times.
