The Story of the Bad Sacrifice

Leviticus 10:1-2

Beth was playing with her stuffed lamb, Baaba, one afternoon.
"Come on, Baaba," Beth said, walking the toy across the living room carpet toward the fireplace, "It's time to sacrifice you to God."
Just then, her mother walked in. "Beth," said Beth's mother, "what are you doing?"
"Baaba and I are playing sacrifice to God, Mother," she answered. Then, pointing to a doll sitting on the couch dressed in a frumpy black dress, "It's because Barbie heard Ken swear and didn't tell anyone. Besides, God likes the way burning animals smell."
Beth's mother frowned and put her hands on her hips. "You really shouldn't be doing that," she said.
Beth stopped making Baaba walk and lowered her head. "Is it because I might get ashes on the carpet?" she asked.
"No, Dear One, that is not why," said her mother, taking a seat on the couch next to Barbie. "Here, bring Baaba and sit on my lap. I will tell you a story."
And this is the story she told:

One day, two of Aaron's sons, Nadab and Abihu, burned some incense because they thought that God would like it. But they did it wrong, so God set them on fire. The fire burned them all up so there was nothing left and they died.

Beth thought about this for a moment. Then she smiled and hugged her mother. "Wow," she said, "if I had burned Baaba wrong, God might have killed me!"
"That's right, Dear One," said her mother. "Be more careful what you play next time."
Beth jumped off her mother's lap and went to play Persecute the Canaanite Animals with Baaba and Barbie. All her questions had been answered.
