Adam Clarke on Jeremiah 9:26

All that are in the utmost corners - כל קצוצי פאה col ketsutsey pheah. These words have been variously understood. The Vulgate translates: Omnes qui attonsi sunt in comam; "All who have their hair cut short." The Targum, Septuagint, Syriac, and Arabic have understood it nearly in the same way; and so our margin. Others think that the insular or peninsular situation of the people is referred to. Dr. Blayney thinks the Arabians are meant, who dwelt in the great desert, between Mesopotamia and Palestine. I really think our marginal reading should be preferred, as expressing the sense of all the ancient Versions.
