Psalm ~ That people may know that You, whose name is Jehovah, You alone are the Most High over all the earth. Jehovah our God is one Jehovah. You must love Jehovah your God with all your heart and all your soul *
This name YHWH is often referred to as the Tetragramaton or (Four-Letters). Historians say that the Jews found this name too Holy to pronounce and so they adopted the man-made custom of pronouncing it "Ha Shem" or "Adonai".
