Parashas Vayeilech · Passuk 31:16
The LORD said to Moses: You are soon to lie with your fathers. This people will thereupon go astray after the alien gods in their midst, in the land that they are about to enter; they will forsake Me and break My covenant that I made with them.
Torah Temimah points to Yoma 52b (יומא נ"ב ב').
English: The first example is the term: “Se’et” (Genesis 4:7). It is unclear whether the verse should be read: “If you do well, shall it not be lifted up [se’et]?” in which case se’et involves forgiveness and pardon; or: “If you do well, but you will lift up [se’et] your sin if you do not do well.” According to this interpretation, se’et is referring to remembrance: If you do not do well, your sin will be remembered. The second uncertain case is the term: “Meshukkadim” (Exodus 25:34). This verse can be read: “And in the candelabrum four cups made like almond blossoms [meshukkadim]”; or as: “Its knops and its flowers made like almond blossoms [meshukkadim].” In other words, the term meshukkadim can be read either with the first part or the last part of the verse. Likewise, the term: “Maḥar” (Exodus 17:9) can be read: “And go out, fight with Amalek tomorrow [maḥar]”. Alternatively, it can mean that Joshua must go out to war with Amalek immediately, and Moses added: “Tomorrow [maḥar] I will stand on the top of the hill” (Exodus 17:9), but today you do not need my prayer. Once again, the issue is whether this term belongs to the beginning or the end of the verse. The fourth case is the term: “Arur” (Genesis 49:7). This verse can be read: “Cursed [arur] be their anger for it was fierce, and their wrath for it was cruel,” on account of Levi and Simeon’s treatment of Shechem. Alternatively, this term, which appears at the beginning of the verse, can be read as the last word of the previous verse: “And in their anger they cut off cursed [arur] oxen” (Genesis 49:6–7). According to this interpretation, “cursed oxen” is referring to the oxen of Shechem, who descended from the accursed Canaan. Finally, the term: “Vekam” (Deuteronomy 31:16) can be read as: “Behold, you are about to sleep with your fathers and rise up [vekam]” at the time of the resurrection of the dead; or: “And this people will rise up [vekam] and go astray.” The Gemara explains the objection presented by this baraita. And wasn’t it taught in a baraita that Yosef of Hutzal is the one called Yosef the Babylonian, as Hutzal is a city in Babylonia; and he is also the person called Isi ben Yehuda, as Isi is a shortened form of Yosef; he is Isi ben Gur Arye, a nickname for Yehuda; he is Isi ben Gamliel; he is Isi ben Mahalalel? And what is his real name? Isi ben Akiva is his name. If they are indeed the same person, Isi ben Yehuda, who is Yosef of Hutzal, says that there are only five verses whose punctuation is unclear, whereas here he adds an additional verse. The Gemara explains: In the Torah itself, there are indeed no more than five verses, but in the Prophets there are more examples of equivocal punctuation, one of which is the verse from I Kings.
Derash on the verse (Bavli sugya) — not a formal named middah of the 13
The Gemara uses this passuk inside a sugya (question, proof, or illustration). That is classical derash, but not labeled here as one of R' Yishmael’s 13 unless the move is explicit.
The prediction that the people will rise and stray after foreign gods is a covenant warning: abandonment of Hashem is described as adultery against the relationship forged in the wilderness.
