מִ֤י חָכָם֙ וְיָ֣בֵֽן אֵ֔לֶּה נָב֖וֹן וְיֵֽדָעֵ֑ם כִּֽי־יְשָׁרִ֞ים דַּרְכֵ֣י יְהוָ֗ה וְצַדִּקִים֙ יֵ֣לְכוּ בָ֔ם וּפֹשְׁעִ֖ים יִכָּ֥שְׁלוּ בָֽם׃
Whoso is wise, let him understand these things, Whoso is prudent, let him know them. For the ways of the LORD are right, And the just do walk in them; But transgressors do stumble therein.
Mishnah Kelim
The beam of a balance and a leveler that contain a receptacle for metal, carrying-stick that has a receptacle for money, a beggar's cane that has a receptacle for water, and a stick that has a receptacle for a mezuzah and for pearls are susceptible to uncleanness. About all these Rabbi Yohanan ben Zakkai said: Oy to me if I should mention them, Oy to me if I don't mention them.
