בראשית, פרק ל׳, פסוק ל״ב

To protect himself from an employer who had already proven untrustworthy, Jacob crafts a highly unusual wage agreement designed to prevent any future deceit. He proposes a model based strictly on the laws of nature: since most sheep are naturally white and most goats are black [רמב״ן, העמק דבר, הירש], Jacob asks to be paid exclusively with the rare, unusually colored minority. By claiming only the anomalies, he ensures there can be no dispute over which animals belong to him. While the general term used for these animals typically includes the young of both sheep and goats [הכתב והקבלה, ספורנו, שפתי חכמים], some interpret the initial specification as referring specifically to mature male goats [אבן עזרא, רד״ק, הטור הארוך].

Jacob carefully details the specific, abnormal markings that will constitute his wages. These include animals speckled with fine, small dots [רש״י, רד״ק, רלב״ג], which some suggest were concentrated around the head and neck [רשב״ם]. He also claims those with large, broad patches, resembling patches sewn onto an old garment [רש״י, רד״ק, שד״ל, הירש]. Finally, he includes the dark-colored sheep, described either as having a reddish-black hue [רש״י, רמב״ן, שד״ל] or as being completely black, so named because their dark coats absorb the heat of the sun [אבן עזרא, רד״ק].

To initiate this agreement, the existing flock must be divided. The primary approach among commentators is that Jacob asks Laban to remove all currently marked animals and keep them for himself, meaning Jacob's wages will consist entirely of future offspring born from the remaining solid-colored flock [רש״י, רשב״ם, רד״ק, בכור שור]. A minority view, however, suggests that Jacob himself is to remove the marked animals to keep as immediate compensation for his past labor [מלבי״ם, פענח רזא]. This strict separation serves two critical purposes. First, it prevents Laban from ever claiming that Jacob stole marked animals from the original flock and passed them off as new births [רש״י, שד״ל, ביאור יש״ר]. Second, it prevents the naturally marked animals from mating with one another. If unusually patterned offspring are suddenly born from a completely solid-colored flock, it will be undeniably clear that this is a result of God's blessing and direct intervention, rather than natural reproduction [רש״י, מזרחי, גור אריה].

However, the immediate execution of the deal reveals Laban's inherent deceitfulness. Jacob's intention was to remove only the young marked animals, leaving the mature ones to breed. Instead, Laban swiftly removes all the mature males and he-goats, actively attempting to reduce Jacob's chances of breeding marked offspring to absolute zero [ספורנו, הכתב והקבלה, חזקוני]. Laban even takes the ring-streaked animals—those with striped legs—despite Jacob not explicitly mentioning them in their conditions [אור החיים]. By aggressively emptying the flock of any natural potential to produce Jacob's wages, Laban fundamentally violates the spirit of their agreement. This blatant attempt to exploit his worker provides the moral and legal justification for Jacob's later use of peeled branches in the watering troughs. Facing a crooked employer who manipulated the terms to leave him with nothing, Jacob is forced to act with permissible cunning to rightfully secure his earnings, outsmarting the man who tried to cheat him [אור החיים, ריב״א, פרדס יוסף].
