איוב, פרק י״ד, פסוק ט׳

The life force hidden within a damaged or felled tree is remarkably resilient. Sometimes, the slightest stimulus is enough to awaken it to fresh, vibrant growth. A tree does not necessarily require an abundance of water to return to life. Even a minimal amount, or merely the lingering humidity and scent of water, is enough to stir its dormant roots and cause it to bloom once more [מצודת דוד, מלבי״ם, ביאור שטיינזלץ, רמב״ן].

As life returns to the stump, it produces new growth. The primary approach among commentators is that this growth takes the form of fresh branches and shoots, rather than an agricultural crop [רש״י, מצודת ציון, אבן עזרא, רמב״ן, רלב״ג]. Specifically, these are the new boughs that sprout directly from the root after the original trunk has been cut down [מלבי״ם]. This renewed growth is so lush and robust that the tree develops large, healthy branches, making it appear exactly like a young, freshly planted sapling [רמב״ן, מצודת דוד, ביאור שטיינזלץ, מלבי״ם].

Beyond the physical revival of a tree, this imagery extends to a spiritual dimension concerning the repair of the human soul. In this framework, water symbolizes the Torah. If a person has sinned and feels unable to engage in Torah study themselves, they can still absorb its life-giving moisture by supporting someone who does. By sustaining a Torah scholar, the individual experiences the restorative scent of water. The new branches that sprout represent a son or a student who acts as a living extension of that person. God, in His infinite mercy, views the righteous actions of this new branch as if the sinner's own soul had been entirely replanted and completely restored [אלשיך].
