• That there is an order to the letters. In fact, each letter is also a number.
• That there is meaning to each letter. In fact, the letter derives it's meaning from the strokes which form it.
• That God has a purpose in the things he doesn't say. It is foreign to the Greek mind. The things that are not said can be interpreted by the same rules which guide interpreting the things that are said.

The unspeakable name of God
The aleph is a silent letter. It's formation is "God spoke and created the heavens and the earth". In Genesis 1:1 it is also an invisible letter. It is invisible and silent to say that when God spoke and created the heavens and the earth, there was no one there to see or hear him do it.

The aleph also contains the name of God. The strokes forming it are יוי which might be pronounce "ee-oo-ee" which sounds almost like יהוה Yahweh; the name God said Moses should use for him. The name he had before the beginning was unpronounceable because there was no one to pronounce it. God did not command us not to say his name. His name was unspeakable because we were not there.
