Exodus 22:29-31

“You must not hold anything back when you give me offerings from your crops and your wine. “You must give me your firstborn sons. “You must also give me the firstborn of your cattle, sheep, and goats. But leave the newborn animal with its mother for seven days; then give it to me on the eighth day. “You must be my holy people. Therefore, do not eat any animal that has been torn up and killed by wild animals. Throw it to the dogs.
