This passage reveals two types of temptation: one that suddenly strikes even the righteous with unexpected calamity, overwhelming them so quickly that they scarcely realize they have stumbled until they have already fallen; and another that creeps in gradually through gentle whispers, leading the soul of the resistant to corruption. In this case, it is not the severity of temptation but its subtlety that drains the strength of righteousness.
Thus, while one type of temptation can swiftly cast a person down, we can affirm: when the mountain falls, it is cast away, just as a righteous mind, grounded in virtue, can suddenly be led into sin by a sudden urge. Additionally, there exists another form of temptation that insinuates itself softly into the human heart, eroding determination: the waters carry away the stones. For instance, the smooth and enticing flattery of lust can drain away the resolve of the soul, gradually infiltrating and eroding the firmness of purpose.
Therefore, it is aptly stated: as the waters erode the earth gradually, so does persistent sinful behavior subtly undermine even the strongest mind. Hence, it is true: You bring destruction upon humanity when You allow sudden temptations to seize a righteous person, who stands firm in faith. The moment a righteous mind turns towards evil, 'the mountain falls away,' and 'the rock is removed from its place.' Similarly, when a slow yet persistent temptation prevails, 'the waters carry away the stones, and as they are washed away bit by bit, the earth is eroded,' for the resolute mind is softened when faced with quiet enticements.
Let us observe how David exemplified the 'high mountain'; elevated to contemplate the profound mysteries of God through prophetic insight, he nonetheless experienced a sudden downfall. Driven by lust, he took another man's wife and orchestrated her husband’s demise, causing sorrow within his own ranks. The mountain fell away when the mind, once immersed in divine mysteries, succumbed to sudden temptation and was contaminated by vile desires, leading the prophet's mind to shut itself off from heavenly truths.
Moreover, consider how the waters erosionarily carry away the stones, leading to ruin as exemplified by Solomon. His numerous indiscretions with women resulted in the construction of idol temples, turning away from God. His indulgence led not just to the corruption of flesh but an overall spiritual decline, mirroring the erosion spoken of: 'the waters carry away the stones, and bit by bit the earth is corroded.' Through the gradual encroachment of sin, the earth of his heart crumbled.
Thus, let blessed Job recognize the different forms of temptation, whether they arise suddenly with great intensity or creep along gently for an extended period. Observing the falls of others, he should gather insight, declaring: surely when the mountain falls, it departs, and the rock moves from its place; the waters carry away the rocks, and little by little the earth is eroded, which leads to the ruin of man. Just as these elements may come crashing down suddenly or be gradually eroded by the waters of existence, so too can You, Creator of rational beings, either overthrow them through sudden provocation or through long-term yet subtle temptations. And He vividly illustrates this intelligent being in the next line, stating:
