The quality of humility is more praiseworthy than any other good quality.

Rabbi Yehoshua ben Levi says: Humility is greater than all the other positive qualities.

Who is destined for the World to Come? One who is modest and humble, who hunches forward when he enters and hunches forward as he exits, and who studies Torah regularly, and who does not take credit for himself.

Rabbi Meir says:… And be humble before every person.

This is the adage that people say: A coin in an empty barrel calls: Kish, kish. (Avoda Zara 20b; Sanhedrin 88b; Mishna Avot 10:4; Bava Metzia 85b)
