내가 이 이십년에 외삼촌과 함께 하였거니와 외삼촌의 암양들이나 암염소들이 낙태하지 아니하였고 또 외삼촌의 양떼의 수양을 내가 먹지 아니하였으며
Rashi on Genesis
לא שכלו means HAVE NOT MISCARRIED — Similar are: (Hosea 9:14) ‘‘a miscarrying (משכיל) womb”; (Job 21:10) “his cow calveth and casteth (תשכל) not her calf”.
Rashbam on Genesis
לא שכלו, neither because of any lack of adequate grazing nor due to careless supervision
Sforno on Genesis
רחליך ועזיך לא שכלו, you have found me as possessing the very reverse of the characteristics of a thief. Not only did I serve you faithfully, but I have treated you even better than fairness dictates. I have endeavoured with all my skill to prevent your sheep from giving birth to premature, and stillborn young.
