He wrote "Although the consonants of this name are well known, its proper vocalization is not rendered by tradition. Some pronounce its first part Abgitaẓ, and others Abigtaẓ, and the last part is sometimes read Shakvaẓit, and sometimes Shekuẓit, but there is no definite proof." This variation in pronunciation was understood by Joshua Trachtenberg to indicate that this version is quite ancient, the vowels in Hebrew being easily lost over time.
