Exodus 34:25-27

Darby Translation

²⁵ —Thou shalt not offer the blood of my sacrifice with leaven; neither shall the sacrifice of the feast of the passover be left over night until the morning.

²⁶ —The first of the first-fruits of thy land shalt thou bring into the house of Jehovah thy God. Thou shalt not boil a kid in its mother's milk.

²⁷ And Jehovah said to Moses, Write thee these words; for after the tenor of these words have I made a covenant with thee and with Israel.
