29 and over the herds that are feeding in Sharon 'is' Shitrai the Sharonite; and over the herds in the valleys 'is' Shaphat son of Adlai; 30 and over the camels 'is' Obil the Ishmeelite; and over the asses 'is' Jehdeiah the Meronothite; 31 and over the flock 'is' Jaziz the Hagerite; all these 'are' heads of the substance that king David hath.
Matthew Henry's Commentary on 1 Chronicles 27:29-31
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.
