Commentary for Bava Metzia 167:12

Reish Lakish saw him: As [Reish Lakish] was a brigand.

If you return, etc.: From this, Rabbenu Tam said that Reish Lakish knew much at first, except that he removed the yoke of Torah [from himself], became an ignoramus and occupied himself with brigandry. Since he said, "If you return" - it implies, being like [you were] at first, and not to remove the yoke of Torah from upon you. And also [since] he said, "What benefit did you provide me, there they called me, Master" - meaning at first they also called me, Master, except I forgot [my learning]. And that which [Rashi] explained - "Master," is the master of the brigands - does not appear [correct]. Even though [it is true] that we find in Tractate Avodah Zarah (17b), "What is the reason they call you, Master? I am the master of weavers." And this is [also the explanation of] that which we say in the chapter [entitled] Kol Kitvei (Shabbat 119b), "Said Reish Lakish to Rabbi Yehudah Nesiah, 'So have I received it from my fathers' - and some say, from your fathers - 'any city that does not have children in a rabbi's school, etc.'" This implies that before Rabbi Yochanan taught him, he studied from others.

Shevar: He jumped.

If you return: Later it is shown that he married [her]; as it says, "His sister came and she cried in front of him." And [Reish Lakish] was not concerned about, perhaps they will say that this one returned (repented) because of this, in the way that it was a concern later (Bava Metzia 85b).

He said: Rabbi Yochanan.

Your strength is fit for Torah: How proper is your strength to carry the yoke of Torah.

Shufrech: Your beauty.

For women: It is suitable for women.

But he was unable to jump, as at first. For from when he accepted the yoke of Torah upon himself, his strength weakened.
