Tana deBei Eliyahu Rabba 26a as quoted in Sefaria: This is what God said to Israel: My children what do I seek from you? I seek no more than that you love one another, and honor one another, and that you have awe for one another.
Seder Eliyahu Rabba 26 (comment on the verse “and you shall love the L-rd your God”):
Make the Name of Heaven beloved by human beings. Do this by the way in which you conduct your business in the marketplace with others so that they will say, ‘Fortunate are those who have studied Torah! See how pleasant are their deeds, how lovely their ways! Let us also learn Torah and teach it to our children...’
Thus it has been said, ‘One should distance oneself from stealing from Jews and non-Jews, from anyone in the market. For if one begins by stealing from non-Jews, they will eventually steal from Jews as well...If they spill the blood of a non-Jew eventually they will shed that of a Jew as well. The Torah was not given for that but in order to sanctify God’s great Name...‘And you shall proclaim My greatness among the nations (Isaiah 66:19).’
(ו) יְהוֹשֻׁעַ בֶּן פְּרַחְיָה וְנִתַּאי הָאַרְבֵּלִי קִבְּלוּ מֵהֶם. יְהוֹשֻׁעַ בֶּן פְּרַחְיָה אוֹמֵר, עֲשֵׂה לְךָ רַב, וּקְנֵה לְךָ חָבֵר, וֶהֱוֵי דָן אֶת כָּל הָאָדָם לְכַף זְכוּת:
(6) Joshua ben Perahiah and Nittai the Arbelite received [the oral tradition] from them. Joshua ben Perahiah used to say: appoint for thyself a teacher, and acquire for thyself a companion and judge all men with the scale weighted in his favor.
וכן אמרו רז״ל והוי דן את כל האדם לכף זכות והוי מקבל את כל האדם בסבר פנים יפות ואמרו מאד מאד הוי שפל רוח ואמרו יהי אדם רך כקנה ואל יהי קשה כארז לפיכך זכה קנה לחתוך ממנו קולמוס לכתוב בו ס״ת תפילין ומזוזות. Similarly, our sages taught "judge every man favorably" (Avos 1:6), "receive every person with a cheerful countenance" (Avos 1:15), and "Be very, very lowly of spirit" (Avos 4:4), and "One should always be flexible as a reed and not unyielding as a cedar. This is why the reed has merited to have made from it a quill to write a Sefer Torah, Tefilin and Mezuzot" (Taanis 20b). From "Duties of the Heart," 6th Treatise on submission, 10.8, Bachya Ibn Pakuda
