Hygiene of the Person

619. Strict habits of cleanliness should be observed. Many, while well, will not take the trouble to keep in a healthy condition. They neglect personal cleanliness, and are not careful to keep their clothing pure. Impurities are constantly and imperceptibly passing from the body, through the pores, and if the surface of the skin is not kept in a healthy condition, the system is burdened with impure matter. If the clothing worn is not often washed, and frequently aired, it becomes filthy with impurities which are thrown off from the body by sensible and insensible perspiration. And if the garments worn are not frequently cleansed from these impurities, the pores of the skin absorb again the waste matter thrown off. The impurities of the body, if not allowed to escape, are taken back into the blood, and forced upon the internal organs.—How to Live 4:60.HL 143.1

620. In regard to cleanliness, God requires no less of his people now than he did of ancient Israel. A neglect of cleanliness will induce disease.—How to Live 4:61.HL 143.2

621. The ten commandments spoken by Jehovah from Sinai cannot live in the hearts of persons of disorderly, filthy habits. If ancient Israel could not so much as listen to the proclamation of that holy law, unless they had obeyed the injunction of Jehovah, and had cleansed their clothing, how can that sacred law be written upon the hearts of persons who are not cleanly in person, in clothing, or in their houses? It is impossible. Their profession may be as high as heaven, yet it is not worth a straw.... All who meet upon the Sabbath to worship God should, if possible, have a neat, well-fitting, comely suit to wear in the house of worship. It is a dishonor to the Sabbath, and to God and his house, for those who profess that the Sabbath is the holy of the Lord, and honorable, to wear the same clothing upon the Sabbath that they have worn through the week while laboring upon their farms, when they can obtain other.—How to Live 6:59.HL 143.3
