Exodus 23:20 YLT

¹⁸  'Thou dost not sacrifice on a fermented thing the blood of My sacrifice, and the fat of My festival doth not remain till morning;

¹⁹  the beginning of the first-fruits of thy ground thou dost bring into the house of Jehovah thy God; thou dost not boil a kid in its mother's milk.

²⁰  'Lo, I am sending a messenger before thee to keep thee in the way, and to bring thee in unto the place which I have prepared;

²¹  be watchful because of his presence, and hearken to his voice, rebel not against him, for he beareth not with your transgression, for My name 'is' in his heart;

²²  for, if thou diligently hearken to his voice, and hast done all that which I speak, then I have been at enmity with thine enemies, and have distressed those distressing thee.
