Augustine of Hippo
He described what he referred to as fire, equating it with anger, even though fire can also cause harm to many. What, then, is the implication of his statement, ‘The Lord heard, and delayed’? Did He postpone leading them into the promised land where they were meant to go? What could have been accomplished in a matter of days, yet due to their transgressions, they had to wander in the wilderness for forty years? If this is the case, was it the people who delayed, rather than those who tested and slandered God, since all of them perished in the wilderness while their descendants entered the promised land? Or did He postpone the consequences to first appease the desires of the faithless, to avoid giving them the impression that He was unable to fulfill their requests? Then He heard, and He held back His wrath: and after executing what they believed He could not accomplish, His anger was kindled against Israel.
