Adam Clarke on Ecclesiastes 2:7

Servants and maidens - For my works, fields, folds, and various domestic labors.

Servants born in any house - Besides those hired from without, he had married couples in the precincts of his grounds, palaces, etc., who, when their children grew up, got them employment with themselves.

Great and small cattle - Oxen, neat, horses, asses, mules, camels, and such like; with sheep and goats. And multitudes of most of these he needed, when we are told that his household consumed daily ten stall-fed oxen, with twenty from the pasture, with a hundred sheep; besides harts, roebucks, fallow deer, fatted fowls, and other kinds of provision, Probably, such another court for splendor and expense was not in the universe.
