For GOD’s anger will flare up against you, shutting up the skies so that there will be no rain and the ground will not yield its produce; and you will soon perish from the good land that GOD is assigning to you.
וחרה אף ה'. תניא, רבי ישמעאל אומר, נאמר כאן וחרה אף ה' ונאמר להלן (פ' משפטים) וחרה אפי והרגתי אתכם בחרב, מה להלן חרב אף כאן חרב [מכילתא פ' משפטים]
English: It was taught: Rabbi Yishmael says: It is said here, “the anger of Hashem will burn,” and there (Mishpatim), “My anger will burn and I will kill you with the sword.” Just as there the sword is stated, so here too the sword is implied. [Mekhilta on Mishpatim]
On the daf / in context: Torah Temimah places this derasha on Devarim 11:17. The Core Text is the words of Chazal (as transmitted in the source named above).
