3. We have learned this: it is forbidden to approach all who fail to toil in Torah, and it is forbidden to be partners with him or do business with him, and one must surely not travel with him on the way, since he lacks Faith. We learned that one who walks along the road without mentioning words of Torah endangers his life. This is all the more the case for he who befriends on the road someone who lacks Faith, BECAUSE he himself does not properly honor his Master, nor even his own, as he shows a lack of concern for his own life.
3. דְּהָכִי תָּנֵינָן, כָּל מַאן דְּלָא אִשְׁתָּדַּל בְּאוֹרַיְיתָא, אָסִיר לְמִקְרַב לְגַבֵּיהּ, לְאִשְׁתַּתְּפָא בַּהֲדֵּיהּ, וּלְמֶעְבַּד בֵּיהּ סְחוֹרְתָּא, וכ"ש לְמֵהַךְ עִמֵּיהּ בְּאוֹרְחָא. דְּהָא לֵית בֵּיהּ מְהֵימְנוּתָא. תָּנֵינָן כָּל ב"נ דְּאָזִיל בְּאוֹרְחָא, וְלֵית עִמֵּיהּ מִלֵּי דְּאוֹרַיְיתָא, אִתְחַיָּיב בְּנַפְשֵׁיהּ. כ"ש מַאן דְּאִזְדַּוָּוג בְּאוֹרְחָא, עִם מַאן דְּלֵית בֵּיהּ מְהֵימְנוּתָא, דְּלָא חָשִׁיב לִיקָרָא דְּמָארֵיהּ וְדִידֵיהּ דְּלָא חָס עַל נַפְשֵׁיהּ.
