The Threefold Repetition of God's Name

In the Hebrew, it's Yahweh, bless you and keep you. So of course, Yahweh is the subject of everything that's going on here. And then there's sort of a crescendo as you go through this because in Hebrew, the first line is only three words. The second line is five words and the third line is seven words. When they utter these words or God utter these words through them, then these words actually impart that of which they speak.
