Rashi: They will hold the ways ¹ . This is like "va'Yilafes Shimshon", "va'Yecherad ha'Ish va'Yilafes" - Rus held him.

Ibn Ezra: They will be distorted. This is like "va'Yilafes Shimshon", "va'Yecherad ha'Ish va'Yilafes."

Malbim (18, 20): [The overflowing river] will flood and seize anyone in its way. This is the first betrayal. Initially they sat on the ground with him for seven days, without a word. They were like a frozen river, which does not move. It is as if it is made for people to walk on, like dry land. Iyov thought that he can speak as much as he wants, and they will be silent. However, after he was heated, they became like a flooding river that inundates all in its way, Tzadik or Rasha. They declared Iyov to be guilty, and did not distinguish between good and evil.

Ibn Ezra: The rivers will rise in vapors. The nature of water is to descend. When it returns to be vapor, it rises and is lost.

Malbim (18, 20): Later, the water that flooded will dry, become vapors that rise in the air and are lost. This is the second betrayal. Iyov thought that in the debate he will find cold water that flows from springs of Chochmah and Da'as, and quench his thirst from their words. He heard only futile words of folly.
