| In the Cabala, the Quaternical system is the Tetragrammaton, the four-letter name of God, commonly pronounced Yahweh or Jehovah. |
| Not only are our sources, indicating the pronunciation of the Tetragrammaton, limited, but we are also hamshackled by certain time constraints. |
| Depending whom you ask, the rule pertains to any version of the name of God, or only the tetragrammaton, or only the tetragrammaton in Hebrew characters. |
| In the daily priestly blessing, the Tetragrammaton was vocalized with the vowel points associated with the name Adonai. |
| That is the Holy Four, the Tetragrammaton of the Kabbalists! |
| Similarly, it is customary to write Yehudah with an aleph rather than a final hey, lest one accidentally leave out the letter dalet and write the Tetragrammaton. |
