בראשית, פרק ל׳, פסוק ל״ז

Faced with his father-in-law's relentless deceit, Jacob is forced to take matters into his own hands. After they reached a labor agreement, Laban secretly removed all the spotted and speckled animals from the flock, leaving Jacob without the very sheep that were supposed to serve as his wages. To secure his rightful earnings, Jacob employs a strategy that blends natural effort, practical wisdom, and a reliance on divine intervention, placing specially prepared branches in front of the flocks as they mate.

The primary approach among commentators is that Jacob’s actions were entirely justified. Because Laban had violated their conditions and removed the speckled animals that could have served as a natural visual stimulus for the flock, Jacob was well within his rights to use any means necessary to produce the agreed-upon offspring and secure his wages [רמב״ן, הטור הארוך, אלשיך, דעת זקנים, מלבי״ם]. A complementary perspective suggests that Jacob never actually placed these branches in front of Laban's flock. Instead, he only set them before the miraculously born speckled sheep he had already acquired. His goal was to ensure their offspring would share the same distinct markings, thereby preventing Laban from ever claiming that Jacob had stolen solid-colored animals [רד״ק, רמב״ן].

The mechanism behind the branches relies on a natural concept: the visual images present before animals during mating are imprinted on their imagination, directly influencing the appearance and color of their offspring [רקנאטי, רבנו בחיי, צאינה וראינה]. However, commentators agree that the absolute success of this strategy could not have occurred without miraculous intervention and direct oversight from God. Jacob had previously seen an angel in a dream revealing spotted and speckled sheep. Therefore, placing the branches was essentially a symbolic, physical action designed to bring a prophetic promise into reality. This mirrors the practice of prophets who perform tangible acts to ground and establish their prophecies [הכתב והקבלה, ביאור יש״ר, רש״ר הירש].

The specific materials Jacob used were critical to his success. He gathered branches from specific trees, including the almond tree [אבן עזרא, רש״י, רלב״ג, פענח רזא] and the plane tree [רש״י, רלב״ג, מחוקקי יהודה]. He also selected branches from the poplar tree [רש״י, מזרחי, שפתי חכמים]. Jacob specifically chose the poplar while it was still fresh and moist, because its inner whiteness is only clearly visible in a fresh state, unlike other trees whose wood remains white even when dry [בכור שור, חזקוני]. To prepare these branches, Jacob peeled away strips of the dark outer bark to expose the white wood underneath [רש״י, רד״ק, רלב״ג], though some interpret this action as splitting or branching the wood [שד״ל, חזקוני]. By selectively stripping the bark, he created striped and spotted patterns on the branches, forming a precise visual model for the flock [רש״י, רשב״ם, רד״ק, ביאור יש״ר]. The exact locations where he peeled the wood—whether at the top, the bottom, or in specific spots—directly guided the specific patterns of the spots on the offspring that would be born [רבנו בחיי, מחוקקי יהודה].
