Exodus 23:18-20 Darby Translation (DARBY)
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 land 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 in the way, and to bring thee to the place that I have prepared.
