Ephraem the Syrian
To ensure that sin is not overlooked lightly and that forgiveness does not lead to greater harm, God informs Moses of His intention to annihilate the Israelites. This serves a purpose: when Moses intercedes on their behalf and their transgression is absolved, this act of mercy will hold greater significance for the people, and Moses will be esteemed more highly for his prayers. "Behold, My angel shall go before thee," indicating that an angel will precede you in My place, "and in the day of My visitation by his hand I will visit their sins upon them." This declaration not only offers encouragement but also serves as a dire warning to the Israelites. "And behold, I will send My angel before thee—be cautious of him, for My name is in him" (Ex. 23:20-21). Since he is carrying out the work of God, the divine name is associated with him.
