Or HaChaim on Numbers 6:25/אור החיים על במדבר ו׳:כ״ה

1 יאר ה׳ פניו, "May the Lord make His face shine upon you." This means that there should not be a "curtain" dividing between Israel and their Father in Heaven.

2ויחנך, "and be gracious unto you." Please refer to what I have explained on the meaning of the word חן in my commentary on Genesis 39,21, "G'd was with Joseph and he caused him to enjoy grace, etc."
