References commonly use modern Hebrew type for ancient Aramaic and Hebrew legends. The chart below may be helpful for reading and understanding these legends. Hebrew is written from right to left, and has only consonants. Most Hebrew words have a three letter root.
Hebrew is traditionally written without vowels/dots (Nikudot). For example the "Bet" has a dot in the center while the "Vet" lacks the dot. The Vav is a "V" with two vertically aligned dots under it, a "O" with a dot on top and a "U" with a dot in the middle left. The Kaf has a dot in the center, while the Khaf/Chaf has none. The Pe has a dot in the center while the Fe has none. The Shin has a dot in the upper right , while the Sin has one in the upper left. The Tav has a dot in the center while the Sav has none, The Tav/Sav is only in the Askenazi accent, the Sephardi accent does not recognize the Sav, both are pronounced Tav. Modern Israel has adopted the Sephardi accent and the Sephardi accent is considered closest to ancient Hebrew. Certain letters have a "final" form (Sofit) that is only at the end of a word, such as the second "Khaf", second "Mem", second "Nun", the second "Fe" and the second "Tzade". There is a difference between the Alef and the Ayin, the Ayin is gutteral and the associated vowel sound comes from deeper in the throat.
The Hebrew letters also have numeric values. For example, on top of the chalice on the Bar Kochba shekels, you will see (from right to left) Shin Alef, Shin Bet Shin Gimel,. Shin Daled or Shin Hei. Shin the first letter of the word Shana (Shin Nun Hei) or Year and Alef = 1, Bet = 2, Gimel =3, Daled =4 & Hei = 5.
