Special officers were set over the vineyards and the stores of wine. The שׁ in שׁבּכּרמים is a contraction of אשׁר: "over that which was in the vineyards of treasures (stores) of wine." The officer over the vineyards, Shimei, was of Ramah in Benjamin (cf. Joshua 18:25); he who was over the stores of wine, Zabdi, is called השּׁפמי, probably not from שׁפם on the northern frontier of Canaan, Numbers 34:10, the situation of which has not yet been discovered, but from the equally unknown שׁפמוה in the Negeb of Judah, 1 Samuel 30:28. For since the vineyards, in which the stores of wine were laid up, must certainly have lain in the tribal domain of Judah, so rich in wine (Numbers 13:23.; Genesis 49:11), probably the overseers of it were born in the same district.

And over the vineyards was Shimei the Ramathite: over the increase of the vineyards for the wine cellars was Zabdi the Shiphmite:

27:27 Vineyards - Over the workmen and labourers in the vineyards; as the next officer is over the fruit of the vineyards. In like manner, one man was over the labourers in the fields, ver.26, and another over the fruits of the fields put into stores.

over the increase...: Heb. over that which was of the vineyards

27. the vineyards-These seem to have been in the vine growing districts of Judah, and were committed to two men of that quarter.

wine-cellars-The wine is deposited in jars sunk in the court of the house.

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.
