Exodus 34:24-26

Revised Standard Version

²⁴ For I will cast out nations before you, and enlarge your borders; neither shall any man desire your land, when you go up to appear before the Lord your God three times in the year.

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.”
