We received the Torah 50 days after we left Egypt. Now that we, the Israelites, had our freedom, it was time to figure out what to do with it.
But, of course, you can't do anything you want. You need to be responsible: Don't spend it all in one shopping spree. Don't just buy Starbursts and Warheads. Maybe you can save it for something big, like a bike. Maybe you can even give a dime or two every week to tzedakah from your allowance. One might say that good sense makes good cents! Those spending rules are what it was like to leave Egypt and receive Torah.
God is saying: Use -- don't abuse -- your freedom. Create a meaningful life full of goodness and value.
