Oh the joys and sorrows of working and reaping wages. In verse 8 we are reminded of the injustice rampant in many a workplace. Oppression and cruelty abound in many places where workers aren’t treated well by those for whom they work.
In verse 10 we are reminded one again that some people are never satisfied with their monetary gain. They just want more and more but never find happiness in what they gain. Therefore, they don’t truly want what they get since they never get what they are seeking.
