Leningrad Codex folio 40 verso, Exodus 15:14b-16:3a
This particular page of the Leningrad Codex includes the ending
of "The Song at the Sea" sung by Moses and the Israelites
after they had crossed the sea on dry land, while the Pharaoh
and his army were overwhelmed by the waves of the sea.
The Song celebrates God's work on behalf of his people, Israel, in which he triumphs over their enemies and brings them to his "own possession." As the narrative continues, the people leave the Sea and go to the wilderness of Shur and from there to the bitter waters of Marah. It is at Marah that the water is made sweet (in other words, drinkable) when, at God's instruction, Moses throws a piece of wood into the water. After this saving act of God the people continue on until they come to the wilderness of Sin. As the page ends, the people are beginning to complain of hunger.
