Citing , Rabbi Samuel bar Naḥmani said in the name of Rabbi Jonathan that when a wife summons a husband to his marital duty, they will have children such as were not to be found even in the generation of Moses. For with regard to the generation of Moses, says, "Take wise men, and understanding and known among your tribes, and I will make them rulers over you." But says, "So I took the chiefs of your tribes, wise men and known," without mentioning "understanding" (implying that Moses could not find men with understanding). And says, "Issachar is a large-boned donkey" (alluding to the Midrash that Leah heard Jacob's donkey, and so came out of her tent to summon Jacob to his marital duty, as reported in ). And says, "of the children of Issachar . . . were men who had understanding of the times to know what Israel ought to do." But the Gemara limited the teaching of Rabbi Samuel bar Naḥmani in the name of Rabbi Jonathan by counseling that such behavior is virtuous only when the wife ingratiates herself to her husband without making brazen demands.
