Leviticus 11-15 explains details of many guidelines given to the Israelites to live a holy lifestyle in obedience to their Lord, maintaing "cleanness". These included rules about unclean foods, purification after childbirth, regulations about skin infections, mildew contamination, and unclean bodily discharges. The Lord directed, "You must keep the Israelites separate from things that make them unclean, so they will not die in the uncleanness for defiling my dwelling place, which is among them". In these chapters, the word "unclean" occurs more than a hundred times, and each time refers to restrictions in conduct for the Israelites in order to remain acceptable for worshiping their holy God.
