Moreover the profit of the earth is for all: the king himself is served by the field. Ecclesiastes 5:9 (KJV)
There seems to be a lot of disagreement between scholars on the syntactic make-up of this verse and what it could mean. Provan claims it to be syntactically awkward. (144) This means, that there is a lack of ‘internal coherence’ in this verse wherein it is difficult to relate it to its preceding and following units of thought. (Seow, 204) The verse is like a sudden inclusion of a slogan; and it perhaps needs further amending. But we’ll take Bartholomew’s suggestion and still to a classical reading. The reading is ironic. He writes, “The image evoked is that just rule would facilitate plowed fields throughout the land so that all can benefit from the fruit of the earth. The land should be for all and the king should facilitate justice, but the tone is ironic. The corrupt power relations have spread to the top of the tree and offer no hope of justice for the oppressed.” (186) This reading aligns with the way Henry contrasts the greed of hoarding wealth versus how nature is abundant for everyone else. The folly here is that the labour one puts into hoarding this wealth only strengthens the King who furthers the oppression and corruption on earth.
