This week’s Torah portion is a double portion found in the book of Vayikra, chapters 12 through 15. This parashah is deeply concerned with the matters of ritual purity and impurity, which in Hebrew are termed taharah and tumah. These concepts are often misunderstood in modern thought, for they do not necessarily relate to sin or morality, but to the conditions under which a person may or may not enter the sacred space and approach Alaha in holiness.
