An image inspired by Exodus 15:23-25. The scene takes place in Marah, a harsh desert environment with a bitter water source. There are discontent people standing around, their faces filled with dissatisfaction and despair. An old man, presumably Moses, is fervently praying with a piece of wood clutched tightly in his hand. Following this, he throws the wood into the water, which begins to change, becoming clear and drinkable. As a result, the people's expressions start to shift from despair to awe. The scene should be depicted in a digital art style with a muted color palette to reflect the harshness of the desert environment.
