When you see someone who doesn’t know how to learn by himself but tends to backslide, you must open an approach to Torah for him. Say to him, ‘How can we be obligated to know the wonders which God performed for us and our ancestors?’ This is (the meaning of), “You shall tell:” words of Haggadah are meant to “draw the heart closer.” ⁸⁸ is that it means to draw the heart closer - see Maarechet Heidenheim on the four sons where this interpretation also appears: “The word v'heegadita, "You shall tell," implies that one should tell the story in a way that draws his heart closer. This means one should answer him with soft words and tell him all that the Torah teaches. The Torah doubles the force of the language by saying v'heegadita…laimor, "You shall tell…saying: the first word implies drawing the child's heart closer to the Torah and the second implies in a soft manner.” This is however a later source but it is a common idea - that va’yaged means to draw the heart closer.

Yachol meirosh chodesh:“One might think this was from the beginning of Nisan:'' Explain this passage in the following way: One might think that one is only obligated to teach the person when he first becomes a backslider and has not yet become mired in impurity. But after he becomes impure in his ways, one need not relate to him. Therefore, the Torah states, “On that day.” (Ex. 13:8) that is, when you see him; even if he has been following an evil path for years, one should not avoid him. “If one says “on that day,” one might think it means “while it is still day;” that is, when one has time to teach him. This is because then he would have time to instruct him in the proper way and to convince him to leave his former way. But if one is only able to rebuke him one is not obligated. Therefore the verse teaches, baavur zeh, “Because of this: only when matzah and maror are before him. That is, When you see him leave the right path, you should still have hope that your words might serve some purpose. This is (the meaning of) matzah and maror. Matzah alludes to the right way and the good inclination and maror alludes to the evil way, the evil inclination. If he is entirely wicked, however, “Do not be vexed by evil people,” (Ps. 37:1) just as it is a commandment to speak to someone who will listen, so one should remain silent if the person won’t listen. If you do not know that he is definitely wicked, one should try to bring him close (to Torah). As it is said, “Love your fellow and bring them close to Torah.”⁸⁹ 1:12
