Exodus 23:20 DBY

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.

²¹  Be careful in his presence, and hearken unto his voice: do not provoke him, for he will not forgive your transgressions; for my name is in him.

²²  But if thou shalt diligently hearken unto his voice, and do all that I shall say, then I will be an enemy to thine enemies, and an adversary to thine adversaries.
