Exodus 23:20-22

Young's Literal Translation

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.
