Exodus 34:25-27

Revised Standard Version

²⁵ “You shall not offer the blood of my sacrifice with leaven; neither shall the sacrifice of the feast of the passover be left until the morning. ²⁶ The first of the first fruits of your ground you shall bring to the house of the Lord your God. You shall not boil a kid in its mother’s milk.”

²⁷ And the Lord said to Moses, “Write these words; in accordance with these words I have made a covenant with you and with Israel.”
