Rashi on Genesis 32:25

Menachem (ben Seruk) explains: “a man covered himself with dust”, taking the verb as dust”. It would mean that they were raising the dust with their feet“ אבק connected in sense with through their movements. I, however, am of opinion that is means “he fastened himself on”, and it", and (אביקו) that it is an word, as (Sanhedrin 63b) “after they have joined (Menachot 42a) “and he twined (the “Fringes”) with loops”. It denotes “intertwining”, for such is the manner of two people who make strong efforts to throw each other — one clasps the other and twines himself round him with his arms. Our Rabbis of blessed memory explained that he was Esau’s guardian ( 77:3).

Rashi on Genesis 32:27

FOR THE DAY BREAKETH, and I have to sing God’s praise at day (Chullin 91b; Genesis Rabbah 78:1).

EXCEPT] THOU BLESS ME — admit my right to the blessings which my father gave me and to which Esau lays claim.

Mishnah Chullin 7:6

It applies to clean animals but not to unclean. Rabbi Judah says, even to unclean animals. Rabbi Judah said: was not the sciatic nerve prohibited from the time of the sons of Jacob, and at that time unclean animals were still permitted to them? They replied, this law was ordained at Sinai but was written in its proper place.

Bavli Berachot 5a

Incidental to the verse, “Tremble, and do not sin,” the Gemara mentions that Rabbi Levi bar Ḥama said that Rabbi Shimon ben Lakish said: One should always incite his good inclination against his evil inclination, i.e., that one must constantly struggle so that his evil inclination does not lead him to transgression, as it is stated: "Tremble, and do not sin." If one succeeds and subdues his evil inclination, excellent, but if he does not succeed in subduing it, he should study , as alluded to in the verse: “Say to your heart.” If he subdues his evil inclination, excellent; if not, he should recite Shema, which contains the acceptance of the yoke of God, and the concept of reward and punishment, as it is stated in the verse: “Upon your bed,” which alludes to Shema, where it says: “When you lie down.” If he subdues his evil inclination, excellent; if not, he should remind himself of the day of death, whose silence is alluded to in the continuation of the verse: “And be still, Selah.”
