Obil
Obil appears once in the lists of officials assigned to David's royal estate. He is named as the Ishmaelite placed over the king's camels.
Camel Keeper for David
The administrative roster of 1 Chronicles 27 names the men who oversaw David's various herds, fields, and stores. Obil's position is specific — animal-by-animal, the responsibilities are parceled out: "and over the camels was Obil the Ishmaelite: and over the donkeys was Jehdeiah the Meronothite: and over the flocks was Jaziz the Hagrite" (1Ch 27:30).
The Ishmaelite designation is part of a wider pattern in the same list, where neighboring peoples — an Ishmaelite, a Meronothite, a Hagrite — are entrusted with the royal livestock. Beyond this office, the text supplies no further information about Obil.
