The Jews are bitten by snakes after complaining again in the desert. At G-d's instruction, Moses builds a copper snake so that the Jews can look at it and be healed. What message was G-d trying to send to them -- and to us -- and how can that message help keep us healthy?
The tale of the copper serpent is not simply about the destructive power of sin; it is about our capacity to grow, and ultimately triumph, in spite of it.
Bring a perfect red heifer, God says. One that's never worked the field. Give the cow to the priest Eleazar, who must take it outside the camps of Israel and have it slaughtered.
