 i read in the first book of the torah that the prophet jacob peace be upon him when he was tending sheep for his maternal uncle laban as a dowry for his daughter stipulated that he would participate in her offspring so every animal was for jacob and every young one was for laban. so jacob peace be upon him would take the branches of the trees skin half and leave half alone then throw them all into the water that the sheep would drink and he would deliberately send the ram at that time so that it would only give birth to two halves half for them and half for the young one.
وقرأت في السفر الأول من التوراة أن النبي يعقوب عليه السلام أيام رعيه غنما للابان خاله مهرا لابنته شارطه على المشاركة في إنسالها، فكل بهيم ليعقوب وكل أغر للابان، فكان يعقوب عليه السلام يعمد إلى قضبان الشجر يسلخ نصفا ويترك نصفا بحاله، ثم يلقي الجميع في الماء الذي ترده الغنم، ويتعمد إرسال الطروقة في ذلك الوقت فلا تلد إلا نصفين، نصفا بهما ونصفا غرا.
