SOPATER

so'-pa-ter, sop'-a-ter (Sopatros): the Revised Version (British and American) the son of Pyrrhus; the King James Version omits. A man of Berea who is mentioned with some Thessalonians and others as accompanying Paul as far as Asia on his return to Jerusalem after his 3rd missionary journey (Acts 20:4). He is probably the same as the "Sosipater" of Romans 16:21.
