Origen, on Num 33:21

“Removing from Lebna they camped in Ressa.”

“The next stage takes place in Ressa [Rissah], which could be put into our words as "visible or praiseworthy temptation." Why is it that however great the progress made by the soul nonetheless temptations are not taken away from it? Here it becomes clear that temptations are brought to it as a kind of protection and defense. For just as meat, if it is not sprinkled with salt, no matter how great and special it is, becomes rotten, so also the soul, unless it is somehow salted with constant temptations, immediately becomes feeble and soft.”
