בראשית, פרק א׳, פסוק י״א

On the third day of creation, following the shaping of inanimate earth and water, the world experiences a profound leap into the biological realm. The ground is infused with the power of growth, fertility, and reproduction, initiating a living system that develops from the simplest forms to the most complex [מלבי״ם, שטיינזלץ]. This process is not merely physical; a higher spiritual force is appointed over every plant and blade of grass, carefully guiding its growth [רמב״ן, רקנאטי, תורה תמימה].

The divine command directs the earth to sprout and bring forth vegetation from within itself [אבן עזרא, רד״ק, שד״ל, חזקוני]. Commentators offer three primary ways to understand the distinction between the different types of vegetation that emerge. One perspective focuses on appearance, suggesting that the initial greenery represents the collective, mixed blanket of vegetation covering the ground, while the subsequent herbs refer to individual stalks, roots, or specific, distinct species [רש״י, רשב״ם, מזרחי, גור אריה]. Another approach views this as a process of development: the vegetation begins as soft, tender shoots without visible seeds, and matures into herbs once it is fully developed and capable of producing seed [רמב״ן, רד״ק, שד״ל, הכתב והקבלה]. A third viewpoint distinguishes them by their purpose, noting that the initial grasses are primarily intended for animal fodder or are eaten for their leaves, whereas herbs are destined for human consumption or are valued specifically for their edible seeds and kernels [ספורנו, שד״ל, הכתב והקבלה].

The ultimate purpose of all plant life is to ensure its own continuity. Plants grow seeds within themselves so that humans might later plant them elsewhere [רש״י, גור אריה, ביאור יש״ר]. In trees, this process is unique; the seeds and kernels required to plant a new tree are hidden deep within the fruit itself, unlike herbs whose seeds remain exposed [רש״י, רד״ק, גור אריה, הכתב והקבלה]. However, this mandate to reproduce is strictly governed by a divine law dictating that every plant and tree must produce fruit and seeds exclusively of its own species. This foundational principle establishes the Torah's later prohibition against crossbreeding species [רמב״ן, ספורנו, רש״ר הירש]. Although this law is explicitly stated regarding trees, it applies equally to herbs [רשב״ם, רד״ק]. The sages relate that the grasses actually deduced this requirement on their own: they reasoned that if trees, which naturally grow apart, are commanded to separate by species, then grasses, which grow densely packed together, must certainly do so. Every herb immediately obeyed and separated itself, prompting the Prince of the World to offer praise to God [תורה תמימה, אור החיים].

The instruction for the earth to produce fruit-bearing trees sparks a profound discussion. On a literal level, this refers to any tree capable of producing fruit that actually does so, which also includes barren trees whose leaves or fruits serve alternative purposes like medicine, heating, or food for birds [רד״ק, הכתב והקבלה, רמב״ן]. However, the primary approach among commentators points to a fascinating gap between God's command and the earth's execution. God commanded the earth to bring forth a fruit tree where the wood of the tree itself would be entirely edible and taste exactly like its fruit. Instead, the earth altered this design, bringing forth a tree where only the produce is eaten, leaving the wood inedible [רש״י, כלי יקר, רבנו בחיי, ברטנורא].

Various explanations are offered for this deviation. Some suggest the earth simply misunderstood the divine intent, assuming God was asking for two distinct types of trees [משכיל לדוד, דברי דוד]. Others explain that the earth, bound by its dense, material nature, was physically incapable of producing the spiritual perfection required for a tree and its fruit to be equal in stature [גור אריה]. Alternatively, the earth may have acted out of good intentions, making the wood inedible so that humans would not consume the trunks and completely destroy the tree populations [חזקוני]. Despite this alteration, the earth was not punished immediately. It was only later, when the first man sinned by eating from the Tree of Knowledge, that the earth's earlier infraction was joined with his, resulting in a shared curse that forced the ground to sprout thorns and thistles [רש״י, כלי יקר, שפתי חכמים, דברי דוד].

Ultimately, God's will was permanently and absolutely embedded into creation for all generations. The raw power to grow was injected deep into the soil, and all seeds and trees were completely formed and prepared beneath the surface, waiting in perfect readiness to emerge into the open air [רד״ק, מלבי״ם, ברטנורא, אלשיך].
