Leviticus 15:4

4. Every bed The inconveniences of ceremonial impurity are strikingly set forth in this and the following verses. The only posture in which the man did not communicate ceremonial impurity was standing without touching any vessel or utensil. The obstruction to social intercourse, business, and trade must have exceeded one’s conception. The man, while under this disability, could neither sit nor lie down without spreading impurity; nor could he eat or drink without defiling the vessel which he touched; while the grasp of friendship polluted the person of his friend and incapacitated him for the public offices of religion and for communion with his kindred until he had washed his clothes and bathed himself, and waited for the friendly shades of evening to emancipate him from ceremonial bondage. Till his purification he was to be excluded from the camp. Numbers 5:2. In contrast with this burdensome ritual Christianity is appropriately called “the law of liberty.”
