The Church Father Jerome is well-known for his translation (or revision) of the Latin Bible which later was named Vulgate. He did not translate from the Greek as was the case with the so-called Vetus Latina but he sought the Hebrew truth (hebraica veritas). However, this raises the question as to how good his understanding of the Hebrew language actually was. Therefore it is asked where Jerome might have learned Hebrew and who his Jewish interlocutors might have been.(Requires a paid personal or institutional subscription to access.)
