Translations:What was the purpose of the Numbers 5 dusty(or "bitter") water test?/6/en

From Theonomy Wiki

What about the "dust of the temple"? Is there something special (holy, perhaps?) about the dust of the temple which makes the test especially effective? Possibly, but my intuition is that the dust was merely symbolic, and dependent upon a physical temple being present. For a people in which (nearly) every other part of their sacrificial system was tied to the temple/tabernacle, it would be surprising if we did not see this physical connection with the temple.
