Exodus 23:18-20

American Standard Version

¹⁸ Thou shalt not offer the blood of my sacrifice with leavened bread; neither shall the fat of my feast remain all night until the morning. ¹⁹ The first of the first-fruits of thy ground thou shalt bring into the house of Jehovah thy God. Thou shalt not boil a kid in its mother’s milk.

²⁰ Behold, I send an angel before thee, to keep thee by the way, and to bring thee into the place which I have prepared.
