Numbers 31:23 –
that is, all metals that do not burn—must be passed through fire in order to be made ceremonially pure. These metal objects must then be further purified with the water of purification. But everything that burns must be purified by the water alone.
The problem with most people’s understanding of God’s plan in the Old Testament is the constant use of “ceremonially pure” or “clean”. We look at this today and think some major ritual must have to take place to purify things. But was that really the case? And if it was, was it God giving them an example on how to live their lives? Or was this a roundabout way to teach the Israelites how to protect themselves from illness?
If you look at many of God’s “Laws” you will notice many are there for health and welfare of the people. Think about these things then and today. First, then your environment was much different than today. You did not have central plumbing, refrigerators and sewage treatment plants so keeping things clean was of the utmost importance. So many of these laws were put in place for keeping things “ceremonial pure” were to protect the people from disease and illness. So you can see now why cleanliness IS next to Godliness.
Now I keep “harping” on this, but we as Christians should really pay close attention to the Hebraic Law and not look at it as legalistic guidelines. Sacrifices are something Jesus modeled for us cleaning the disciple’s feet. Tithing helps the church survive and grow the kingdom, as well as (with other financial “Laws”) teaches you proper money/asset management. The food “Laws” have been scientifically proven to be the best diet for one’s body. So when people say we don’t need to follow the “Law” anymore, we must rethink that stance.
