惟有聖潔的百姓才能敬拜聖潔的上帝，正因如此，上帝才會頒布一連串處理各種不潔的法規給以色列人。這些法規可分為四大項：飲食條例(說明可食用及不可食用的動物)：生產條例：痳瘋及其他皮膚病變條例：漏症條例。每一種命令之後都附有一般的常規。首先描述的是獻祭者所受到的污染，其次說到他如何重獲聖潔的方式。相當冗長繁瑣的一章－因為聖潔是必須注重細節的！

        一首流行甚廣的民歌一開頭就唱：「不可能，不可能……」當你讀到十一章四十四節的命令：「要聖潔，因為我是聖潔的。」恐怕你也準備和那民歌手輕唱「不可能」吧！
        是不是上帝要求祂的百姓做不可能或根本做不到的事？是不是祂「要聖潔」的要求不合理？以人的觀點看，這個功課真是不可能呢！
        有一點是非常正確的，那就是靠著人自己的力量，活出聖潔的上帝所要求的公義正直，的確是不可能的！但上帝的用意不是要使你挫折，而是要教導你，正如律法的頌布是為了教導每一個以色列人信靠上帝，也正像祂預備獻祭與儀式，是為了祂這些不夠完全的子民一樣，所以祂要教導你單單的靠著完美無瑕的救主－耶穌基督奇妙的幫助，使你能夠到達聖潔的地步。
        保羅認為：「你們既然接受了主基督耶穌，就當遵祂而行」(西2：6)。靠著基督的力量，你能夠過聖潔純全的生活。參考利未記十一章四十四節，完成這個句子：「你們要成為聖潔。(如何？何時？何處？何人？)；因為我是聖潔的。」然後在今天之中，從你的生活裡選定－個範圍，為你能養成聖潔的習慣努力！

痳瘋今昔觀
        今日的痳瘋病(如跛足和畸形)與利未記或新約所說的痳瘋(如白斑症，濕疹或乾癬等)是否相同，至今仍不確定。

上帝住在兩個天堂裹，其中一個是聖潔的心。

English

        Worshiping a holy God demands a holy people. For this reason God gives Israel a series of regulations dealing with ceremonial uncleanness. Four areas are specified: dietary laws (describing edible and nonedible animals); childbirth matters; leprosy and other skin disorders; and bodily discharges. Each set of commands follows a general pattern. The worshiper's defilement is first described, then the means for regaining his purity are prescribed. It's a lengthy, detailed section— because holiness demands attention to detail.

        A popular ballad opened with the words, "It's impossible,,.." And when you read the command in 11:44. "Be holy; for I am holy," you're probably ready to croon right along with the singer!
        Isn't God demanding something impossible and unattainable from His people? Isn't He being unreasonable when He says, "He holy"? Why, from a human point of view, the task seems impossible.
        That is precisely the point! It is impossible by human efforts alone to live up to the righteous demands of a holy God. Hut rather than frustrate you, God wants to teach you. The Law was designed to teach the Israelites to be dependent upon God. Just as He provided sacrifices and rituals for cleansing His less-than-perfect people, so He wants to [each you that only through the supernatural provision of a sinless Savior, Jesus Christ, can you hope to achieve holiness.
        Paul puts it this way; "As ye have therefore received Christ Jesus the Lord [by faith, trusting in Him], so walk ye in him Iby faith, trusting in Him]" (Colossians 2:6). In Christ's strength you can live a holy and pure life. Complete this thought from Leviticus 11:44: "Ye shall be holy [how? when? where? with whom?]; for I am holy." Then work today on developing the habit of holiness in one area of your life.

Leprosy Then and Now —
        It is doubtful that modern-day leprosy (which cripples and disfigures) is the same as Levitical or New Testament "leprosy" (which was a white, scaly disease, much like eczema or psoriasis).

The Lord has two heavens to dwell in, and the holy heart is one of them.
