The Song of the Sea (שירת הים, Shirat HaYam, also known as Az Yashir Moshe and Song of Moses, or Mi Chamocha) is a poem that appears in the Book of Exodus of the Hebrew Bible, at . It is followed in verses 20 and 21 by a much shorter song sung by Miriam and the other women. The Song of the Sea was reputedly sung by the Israelites after their crossing the Red Sea in safety, and celebrates the destruction of the Egyptian army during the crossing, and looks forward to the future conquest of Canaan. The poem is included in Jewish prayer books, and recited daily in the morning shacharit services. The poem also comprises the first ode or hymn of the Eastern Orthodox canon, where it is known as the Song or Ode of Moses. It is also used in the Roman Catholic, Eastern Orthodox, and other Christian liturgies at the Easter Vigil when the history of salvation is recounted. These traditions follow Revelation 15:3 by calling it the "Song of Moses" (not to be confused with the Song of Moses in Deuteronomy). The poem forms part of the sixteenth weekly Torah portion, or parshat Beshalach. The Sabbath on which it is read is known as Sabbath of the Song (שבת שירה). It is one of only two sections of the Sefer Torah (Torah scroll) that is written with a different layout from the normal simple columns. The other section written differently is the Song of Moses at the end of Deuteronomy, in the 53rd weekly portion, or parshat Ha'azinu. The Song of the Sea is noted for its archaic language. It is written in a style of Hebrew much older than that of the rest of Exodus. A number of scholars consider it the oldest surviving text describing the Exodus, dating to the pre-monarchic period. An alternative is that it was deliberately written in an archaic style, a known literary device. As such, proposed dates for its composition range from the 13th to the 5th century BCE. The Ashkar-Gilson Manuscript is a fragment of a 7th or 8th century Torah scroll that contains the Song of the Sea.
