Mishnah 10 - Chapter 4 - Pirkei Avot

Rabbi me'ir omer. Hevei mema'et ba'esek, va'asok battorah. Vehevei shefal ruach bifnei chol adam. Ve'im bittalta min hattorah, yesh lecha betelim harbeh kenegdach. Ve'im amalta vattorah, yesh (lo) sachar harbeh litten lach.

Rabbi Meir said:Engage but little in business, and busy yourself with the Torah. Be of humble spirit before all men. If you have neglected the Torah, you shall have many who bring you to neglect it, but if you have labored at the study of Torah, there is much reward to give unto you

R. Meir says: Diminish (your) occupation [with business or labor] and occupy yourself [primarily] with Torah. And be of lowly spirit before all men, [to learn even from those lesser than you in wisdom.] And if you would be idle [in Torah study], there are many idlers beside you [to assist you in doing so. Or: There are many idlers in the world, the wicked and the savage beasts, through whom the Holy One Blessed be He can bring punishment upon you.] And if you have toiled in Torah He has much reward to give you. [He Himself will reward you, and not a messenger, His attribute of good being greater than that of His punishment.]
