בראשית, פרק ז׳, פסוק ט׳

The gathering of the animals to the ark was not a massive human hunting expedition, but a miraculous event where nature itself responded to divine will. The primary approach among commentators is that the animals traveled from forests and deserts to the ark completely on their own, without any physical effort from Noah. Although Noah was previously instructed to bring the animals, implying active participation, his actual role was limited to guiding them into the ark once they arrived or simply calling them to enter [מזרחי, רד״ק, גור אריה]. This spontaneous gathering solved an enormous practical problem. It spared Noah the impossible task of selecting which specific animals to save without causing chaos or injuring the creatures left behind [שפתי חכמים]. A profound insight emerges from this event: God, who commands human action, also directs the natural world to make fulfilling His will possible. In doing so, He reveals Himself as both the God of morality and the God of nature [רש״ר הירש].

The arrival of the animals in pairs appears to contradict a previous instruction to gather seven of every pure species. Commentators offer several ways to understand this detail. One perspective suggests that arriving in pairs simply describes the absolute minimum requirement, noting that every species, pure or impure, had at least two representatives present [רש״י, מזרחי, שפתי חכמים, ברכת אשר, שטיינזלץ]. Another approach explains that the description of pairs refers to the manner of their arrival rather than the total headcount. Instead of arriving in a chaotic stampede, the animals approached in organized pairs of male and female, including the pure species that ultimately arrived as seven pairs [רד״ק, יריעות שלמה, גור אריה, העמק דבר]. A third view proposes that numerous pairs arrived independently, allowing Noah to select one pair from the impure species and seven pairs from the pure ones [ביאור יש״ר].

A different perspective draws a distinction based on the ultimate purpose of the animals. In this view, two animals of every species arrived spontaneously by the will of God to ensure the survival of their kind. However, Noah had to actively gather the remaining five pure animals himself, as their purpose was for future sacrifices rather than biological continuation [אור החיים]. Others disagree with this division, maintaining that even the additional pure animals arrived on their own [העמק דבר]. The specific arrival of males and females in equal numbers also raises a question regarding the pure species, since in the natural world, a single male can mate with multiple females. The equal pairing was necessary because the extra pure males were not intended for reproduction. Rather, they were designated to be sacrificed as burnt offerings to God after the flood, and religious law dictates that a burnt offering must be a male animal [בכור שור].
