25 And over the king's treasures was Azmaveth the son of Adiel; and over the storehouses in the country, in the cities, and in the villages, and in the towers was Jonathan the son of Uzziah. 26 And over them that worked in the field for tillage of the ground was Ezri the son of Chelub. 27 And over the vineyards was Shimei the Ramathite; and over what was in the vineyards of stores of wine was Zabdi the Shiphmite: 28 and over the olive-trees and the sycamore-trees that were in the lowland was Baal-hanan the Gederite; and over the cellars of oil was Joash. 29 And over the herds that fed in Sharon was Shitrai the Sharonite; and over the herds in the valleys was Shaphat the son of Adlai. 30 And over the camels was Obil the Ishmaelite; and over the asses was Jehdiah the Meronothite. 31 And over the flocks was Jaziz the Hagarite. All these were comptrollers of the substance which was king David's.

Commentary on 1 Chronicles 27:16-34
(Read 1 Chronicles 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.
