As the Jews spread throughout the lands bordering the Mediterranean, they drew upon other languages for their personal names while still retaining Biblical ones, and they were especially prone to adopt names ending in "-el". These new names became exceptionally popular in Italy. To this source must be traced the new name "Ḥushiel", composed on the same plan as the Biblical ones ending in "-el". The kings of the Khazars, so far as their names are known, wavered between pure Biblical names, like Obadiah, and local names, like "Bulan". The Karaites in the same neighborhood adopted Tatar names, one of them being known as Toktamish; but elsewhere Karaite names are mostly Arabic and Persian.
