Clean, Holy, Set Apart

Numbers 18-20


Back in 1847 a doctor named Ignaz Semmelweis noticed that, through several events, women who had died of postnatal fever had been attended during the birth by doctors who had just done autopsies. Semmelweis came up with the idea that doctors should wash their hands between autopsies and births. And all of us collectively think… well yeah! Of course! But this was not part of the course of a doctor’s day at the time. In fact, many doctors were offended at the suggestion they weren’t clean. Semmelweis was absolutely ridiculed and eventually driven mad. He was placed in an asylum where he died within two weeks, ironically from an infection, after being beaten by prison guards.
Perhaps these doctors should have referred to today’s reading. After discussing the duties of the Levites in Numbers 18, Numbers 19 discusses being “unclean” for 7 days after touching a corpse for any reason. Definitely something these doctors should have taken note of.


Much is said about what is clean and unclean in the Pentateuch. The Israelites certainly benefited physically from not touching dead bodies or eating pork. Some issues of cleanliness could not be helped, such as touching the dead or having a monthly period. In these cases, people were unclean for a time and then had to wash themselves in special ceremonies and offer sacrifices.
But God did not delineate what was clean and unclean just for hygiene’s sake. God also wanted the Israelites to be set apart, different than the rest of the world, holy.


We are to come before Him with clean hands and pure hearts (Psalm 24: 4). But there are times when we become unclean and need someone who can wash us white as snow. Praise God for providing the sacrifice that completely cleans us, His Son, Jesus Christ.


We’ve come a long way since 1847. Hand washing is the first skill nurses have to demonstrate before moving on to other skills. As you wash your hands today, keep in mind the One who cleans you completely!

Reflection Questions

  1. What can we learn from Ignaz? What can we learn from the doctors who ridiculed Ignaz, believing that they themselves were clean?
  2. Does God still want His people today, the church, to be clean, holy and set apart? What does that look like? What does it look like to have a church that is dirty/stained, unholy and blending in with the world?
  3. Are there any common practices today that you think might be making many Christians unclean before the Lord?
  4. What is the only way you can come before God clean? If you accept Jesus as Lord of your life, are there still things you do that make you clean and unclean? How might Numbers have been preparing God’s people for Jesus?

Pure Plates – or Hearts?

Leviticus 11-13

Two of my favorite foods to eat are bacon and shrimp (sometimes together): I absolutely love the smell, taste, and feeling of crunching into a crisp piece of bacon. Shrimp is a delicacy that I enjoy in all different styles of cooking: fried, grilled, or even cold with a side of cocktail sauce. And yet, when I read through today’s Leviticus passage, I find out that the Israelites weren’t supposed to eat either of these very popular items: they are said to be “unclean” for them and were to be avoided… Am I sinning against God by enjoying these dishes?

We must understand the concept of “cleanliness” and the purpose behind the food laws in this book to answer that question. First, what does being “clean” mean in Leviticus? According to scholar Walter Kaiser, “being clean makes a person fit and suitable for entering into the worship of God.” Being clean simply meant that you are in a proper position to enter into God’s presence: it didn’t necessarily mean that you had sinned against Him and were guilty of punishment (although, sinning would certainly make you unclean). For example, in Leviticus 12, a woman who recently gave birth was considered “unclean” until seven days had passed by. Did the woman sin by giving birth to a child, which God commanded for humans to do? (Genesis 1:28) Of course not: this is just one example that being “unclean” didn’t necessarily mean that you had sinned, but that you were just not allowed in God’s holy space for a period of time.

With that understanding, we need to look at the purpose behind the food laws in Leviticus. We are told:

For I am the LORD your God. Consecrate yourselves therefore, and be holy, for I am holy. And you shall not make yourselves unclean with any of the swarming things that swarm on the earth. For I am the LORD who brought you up from the land of Egypt to be your God; thus you shall be holy, for I am holy.” – Leviticus 11:44-45 NASB1995

I am the LORD your God. You shall not do what is done in the land of Egypt where you lived, nor are you to do what is done in the land of Canaan where I am bringing you; you shall not walk in their statutes.” – Leviticus 18:2-3 NASB1995

The entire purpose behind the food laws was for the Israelites to be “holy”, which means “set apart” or “different”: since they worshiped and represented a completely holy God, they were supposed to live differently than the people around them. Although all the animals were given to humanity for food (Genesis 9:3), the Israelites were supposed to look different than those around them. Why? So that people would notice and begin pursuing their holy God. The entire purpose is so that others would come to know the one true God and follow His ways.

So are Christians sinning against God by deliberately disobeying these food laws? Well, Jesus in his ministry redefined what it means to be “clean” and “unclean”: it is no longer based on the food we eat, but the condition of our hearts and behavior towards others. What matters the most is what’s inside the person’s heart, not what they take into their stomach.

He said to them, ‘Are you so lacking in understanding also? Do you not understand that whatever goes into the man from outside cannot defile him, because it does not go into his heart, but into his stomach, and is eliminated?’ (Thus he declared all foods clean.) And he was saying, ‘That which proceeds out of the man, that is what defiles the man. For from within, out of the heart of men, proceed the evil thoughts, fornications, thefts, murders, adulteries, deeds of coveting, envy, slander, pride and foolishness. All these evil things proceed from within and defile the man.’” – Mark 7:18-23 NASB1995


Christians have the same command as the Israelites: to be “holy” like their heavenly Father is holy (Matthew 5:48). However, how we fulfill that command is different: under the New Covenant, we are supposed to be focused on making sure our hearts are pure, rather than our plates, if we want to be useful for God in this world. So, although we are now allowed to enjoy bacon and shrimp, Christians must ask themselves: “has my behavior brought glory to God, or am I unclean and unuseful because of the choices I’ve made and the words I’ve said today?”
