At the feast there were six stone water jars that were used by the people for washing themselves in the way that their religion said they must. Each jar held about 100 liters.
These rules are merely about such things as eating and drinking and ceremonies for washing ourselves. And rules about physical things will last only until the time comes to change them for something better.
So let's come near God with pure hearts and a confidence that comes from having faith. Let's keep our hearts pure, our consciences free from evil, and our bodies washed with clean water.
Moses told the people all the Law said they must do. Then he used red wool and a hyssop plant to sprinkle the people and the book of the Law with the blood of bulls and goats and with water.
