The Hebrew language is derived from 22 letters. The 22 letters also represent the numbering system, as each letter also represents a number. Going back to the earliest form of the language, which was called Paleo-Hebrew, each letter also represents a picture with its associated word concept. It is quite an exciting language and, I believe as do many others, the original language of the human race before the tower of Babel.
Below I have listed the letter, number representation, and the picture/word association. Enjoy!

Below is a chart depicting the modern Hebrew Aleph-Bet. It is known as Aramaic Script. Five of the letters have an additional final form. (The Kaf, Mem, Nun, Peh, and Tsade). If you click on the picture you will find a link to the Jewish Virtual Library, where the picture came from. There you will find additional information about the letters of the Aleph-Bet.
In addition, valuable information can be found at the following link, along with pictures of the Paleo-Hebrew letters.
