Malbim: The Mashal discusses the way of diligence and the way of laziness. Each has Temimus and Akshus. Temimus of diligence is if he works his land and benefits from his hands' labor. He is satiated with bread. This is the good way of diligence. The opposite is one who pursues emptiness and does not do anything. He is satiated with poverty. This is the bad way in laziness. There is a good way in laziness - he should not be too diligent to become rich via theft and murder. This diligence is evil, and the way of an Ikesh. In this, laziness is better. Refer to 28:20:1:2.

Rashi: It is poverty.

Malbim: Refer to 28:20:2:1.
