The Torah, “Numbers” 6:22 – 6:26: The Lord spoke to Moses saying: Speak to Aaron and his sons, saying: This is how you shall bless the children of Israel, saying to them: “May the Lord bless you and watch over you. May the Lord cause His countenance to shine to you and favor you. May the Lord raise His countenance toward you and grant you peace.”
This blessing is said by the Cohanim (priests) on the Sabbath and on holidays. The Cohen (priest) is the most sublime attribute in a person, and if he is connected to the Creator who blesses him, it has a positive effect on all the other attributes a person has. This blessing corrects his whole internal structure and all his desires and intentions
Question: What is the meaning of the words, “and watch over you?”
Answer: The Upper Light, or the Creator, guards us from our egoism. He raises, strengthens, directs, and corrects us. Everything is in the hands of the Light that comes from above and corrects us. As it is written, “May the Lord cause His countenance to shine upon you and favor you.” To favor you means that He will redeem us from the great ego that holds on to us and does not let us ascend.
Everything advances in one direction, and there is nothing else but that.
