The Samaritan alphabet is close to the script that appears on many Ancient Hebrew coins and inscriptions. By contrast, all other varieties of Hebrew, as written by Jews, employ the later 'square' Hebrew alphabet, which is in fact a variation of the Aramaic alphabet that Jews began using in the Babylonian captivity following the exile of the Kingdom of Judah in the 6th century BCE. During the 3rd century BCE, Jews began to use this stylized "square" form of the script used by the Achaemenid Empire for Imperial Aramaic, its chancellery script while the Samaritans continued to use the Paleo-Hebrew alphabet, which evolved into the Samaritan alphabet.
