This verse prohibits wearing clothing made of both wool and linen fibers, known as 'shaatnez,' as it symbolizes a mixture of the sacred and the profane. The law reflects the importance of maintaining purity and separation in various aspects of life, including clothing. It serves as a reminder to the Israelites to uphold God's standards of holiness and avoid syncretism or blending of conflicting practices. The prohibition on shaatnez also underscores the principle of obedience to God's commands, even in seemingly minor details, as a sign of reverence and faithfulness.
