The request made here in Proverbs is brutely honest and shows our true human nature. It is asking for a sufficiency that avoids both extremes of acute poverty and unnecessary riches. Both of which can take us places we don’t want to go. When we have an excess of material things… first, we want more & more, and all these things can cause us to forget Who gave them to us in the first place. Secondly, we start depending on ourselves rather than God to supply our needs…to the point we forget God, hence the question, “Who is the Lord?” But at the opposite end of this request we find severe poverty…where our possessions have been taken away by fire, hurricane, tornado, flood, or some other disaster and we are left with nothing. Being penniless & destitute can push an otherwise law-abiding citizen do things they’re ashamed of just to feed their kids. That’s why the Writer of this Proverb asks for just enough for the day…a regular allotment of not too much & not too little.
