“This is the law for him in whom is a case of leprous disease, who cannot afford the offerings for his cleansing" (v32). Ancient people didn’t divide the world or their lives into secular and sacred categories like we do; the sacred (or supernatural) pervaded everything. Therefore, when someone with a disease got physically well, they offered a sacrifice in the temple and presented themselves to a priest to be pronounced ritually clean/whole. Everyone participated, and a poor person’s simple offering was as effective as a rich person’s.
“And he shall be clean” (14:20). No part of our lives is left outside God’s desire for wholeness: He cares about our physical, mental, spiritual, and emotional health.
