The name of the Ishmaelite who was set over the camels, Obil (אוביל), reminds us of the Arab. abila, multos possedit vel acquisivit camelos. המּרנמי, he of Meronoth (1 Chronicles 27:30 and Nehemiah 3:17). The situation of this place is unknown. According to Nehemiah 3:7, it is perhaps to be sought in the neighbourhood of Mizpah. Over the smaller cattle (sheep and goats) Jaziz the Hagarite, of the people Hagar (cf. 1 Chronicles 5:10), was set. The oversight, consequently, of the camels and sheep was committed to a Hagarite and an Ishmaelite, probably because they pastured in the neighbourhood where the Ishmaelites and Hagarites had nomadized from early times, they having been brought under the dominion of Israel by David. The total number of these officials amounted to twelve, of whom we may conjecture that the ten overseers over the agricultural and cattle-breeding affairs of the king had to deliver over the annual proceeds of the property committed to them to the chief manager of the treasures in the field, in the cities, and villages, and towns.

Over the camels also was Obil the Ishmaelite: and over the asses was Jehdeiah the Meronothite:

30. camels-These were probably in the countries east of the Jordan, and hence an Ishmaelite and Nazarite were appointed to take charge of them.

27:16-34 The officers of the court, or the rulers of the king's substance, had the oversight and charge of the king's tillage, his vineyards, his herds, his flocks, which formed the wealth of eastern kings. Much of the wisdom of princes is seen in the choice of their ministry, and common persons show it in the choice of their advisers. David, though he had all these about him, preferred the word of God before them all. Thy testimonies are my delight and my counsellors.
