In JLAtg the vocalizations of the thematic vowel in the perfect vary between /e/ and /a/ in what is now an apparently haphazard fashion; however, enough evidence is found, especially when combined with the general situation elsewhere in the language (compare, e.g., s.v. ḥrb) to argue that /e/ is properly used in the intransitive instances whereas /a/ is found in the transitive cases.
