Human uncleanness, as described in the Bible, refers to a state of ritual impurity that can affect individuals, rendering them unfit for participation in certain religious activities and requiring specific purification rites. This concept is primarily rooted in the Old Testament, particularly within the Mosaic Law, where various forms of uncleanness are outlined and addressed.

Biblical Basis

The concept of uncleanness is extensively detailed in the Book of Leviticus, which serves as a guide for the Israelites on maintaining holiness and purity. Leviticus 11-15 provides comprehensive instructions on what constitutes uncleanness and the necessary steps for purification. The laws of uncleanness cover a wide range of circumstances, including dietary restrictions, bodily discharges, skin diseases, and contact with dead bodies.

Dietary Laws

Leviticus 11 outlines the dietary laws, specifying which animals are considered clean and unclean. For example, Leviticus 11:4-8 states, "But of those that only chew the cud or have only a split hoof, you are not to eat: the camel, though it chews the cud, does not have a split hoof; it is unclean for you. The rock badger, though it chews the cud, does not have a split hoof; it is unclean for you. The rabbit, though it chews the cud, does not have a split hoof; it is unclean for you. And the pig, though it has a split hoof, does not chew the cud; it is unclean for you."

Bodily Discharges

Leviticus 15 addresses uncleanness related to bodily discharges. Verses 2-3 state, "Speak to the Israelites and tell them: When any man has a bodily discharge, the discharge is unclean. This uncleanness is from his discharge, whether his body allows the discharge to flow or blocks it."

Skin Diseases

Leviticus 13-14 provides detailed instructions on diagnosing and purifying skin diseases, often translated as "leprosy" in older versions of the Bible. Leviticus 13:3 instructs, "The priest is to examine the sore on his skin, and if the hair in the sore has turned white and the sore appears to be deeper than the skin of his body, it is a leprous sore. When the priest examines him, he must pronounce him unclean."

Contact with the Dead

Numbers 19:11 addresses uncleanness from contact with the dead: "Whoever touches any dead body will be unclean for seven days." This form of uncleanness required a specific purification process involving the ashes of a red heifer, as detailed in Numbers 19.

Purification Rites

The purification process for uncleanness often involved washing with water, offering sacrifices, and waiting for a specified period. For instance, Leviticus 15:13 states, "When the man with the discharge is cleansed of his discharge, he must count off seven days for his cleansing, wash his clothes, and bathe himself in fresh water, and he will be clean."

New Testament Perspective

In the New Testament, Jesus Christ addresses the concept of uncleanness, emphasizing the importance of inner purity over ritualistic observance. In Mark 7:18-23 , Jesus explains, "Are you still so dull? He asked. Do you not understand? Nothing that enters a man from the outside can defile him, because it does not enter his heart, but it goes into the stomach and then is eliminated. (Thus all foods are clean.) But He continued: What comes out of a man, that is what defiles him. For from within the hearts of men come evil thoughts, sexual immorality, theft, murder, adultery, greed, wickedness, deceit, debauchery, envy, slander, arrogance, and foolishness. All these evils come from within, and these are what defile a man."

Theological Implications

The laws of uncleanness in the Old Testament served to set the Israelites apart as a holy people, emphasizing the need for purity in approaching God. They also foreshadowed the ultimate purification from sin through Jesus Christ, who fulfilled the Law and provided a means for spiritual cleansing. The New Testament shift from external to internal purity highlights the transformative power of the Gospel, calling believers to a life of holiness rooted in the heart.
