Since the writer of Ecclesiastes has inserted a thought (vs. 8, ch. 6) that is unconnected to either vs.7 or vs.9, I take it then that the object of the appetite has changed. The “eye” and “roving” doesn’t sound like he is referring to food but another appetite that uses the roving eye. “Let each man have his own wife” and keep his sight at home is what he is saying.
