Exodus 34:25-26

“You shall not offer the blood of My sacrifice with leavened bread, nor shall the sacrifice of the Feast of the Passover (Unleavened Bread) be left over until morning. “You shall bring the very first of the first fruits of your ground to the house of the LORD your God. “ Y ou shall not boil a young goat in his mother’s milk [as some pagans do].”
