Cleodemus Malchus

Cleodemus Malchus was a Jewish writer of whom only a few lines survive. He connects the inhabitants of Syria and North Africa with Abraham by identifying them as descendants of three sons whom Abraham had by Keturah: Apheran, Asoureim, and Iaphran. His work appears cited in a quote from Alexander Polyhistor referenced by Josephus in Antiquities of the Jews 1.239-41.
Josephus was cited by Eusebius in his Praeparatio Evangelica 9.20-2.4. According to Robert Doran, "the two texts show minor variations."
