Exodus 34:25-27

American Standard Version

²⁵ Thou shalt not offer the blood of my sacrifice with leavened bread; neither shall the sacrifice of the feast of the passover be left unto the morning. ²⁶ The first of the first-fruits of thy ground thou shalt bring unto the house of Jehovah thy God. Thou shalt not boil a kid in its mother’s milk. ²⁷ And Jehovah said unto Moses, Write thou these words: for after the tenor of these words I have made a covenant with thee and with Israel.
