# Why do you weigh out ... bread, and why do you labor ... satisfy?

"You should not pay money ... bread, and you should not labor ... satisfy" 

# for what is not bread

"for things to eat that are not really food" 

# eat what is good, and delight yourselves in fatness

The people trusting Yahweh for blessing and happiness is spoken of as if they are eating good food that is making them happy.
