Job 9:30. If I wash myself with snow water, and make my hands never so clean.
Snow water was anciently supposed to possess peculiar virtues for cleansing the skin. It was thought that the skin was whitened by it, and that it contracted the fibers and prevented perspiration. “In the fable of Lockman, No. 13, the black man rubs his body with snow in order to make it white. Therefore Mohammed prays, Lord, wash me from my sins white with water, snow, and ice.’” (Umbreit, Version of the Book of Job).
