Exodus 15 is a chapter in the Bible that recounts the triumphant song of Moses and the Israelites after their deliverance from the Egyptians at the Red Sea. The chapter begins with a poetic hymn, often called the "Song of the Sea," praising God for His power and salvation. Moses and the people celebrate how God drowned Pharaoh’s army in the sea, demonstrating His supremacy over earthly powers. The song highlights God’s strength, faithfulness, and guidance, foretelling His promise to lead the Israelites to the Promised Land. Following the song, Miriam, Moses’ sister, leads the women in a joyful dance with tambourines, echoing the victory refrain. The chapter then shifts to the Israelites’ journey into the wilderness, where they encounter bitter water at Marah. After the people grumble, God instructs Moses to purify the water by throwing a piece of wood into it, making it drinkable. The chapter ends with God promising to protect the Israelites from disease if they obey Him, establishing a covenant of care as they continue toward Elim, an oasis with water and palm trees.
