Parashas Eikev · Passuk 11:17
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.
Torah Temimah points to Taanit. (שם שם — same source as the previous unit).
TT lemma: ועצר את השמים (unit 3 of 9).
English: Rav Chisda said: Rains that fell only enough to rinse the mouth of a barrel do not count under “He will shut up the heavens.”
Derash on the verse (Bavli sugya) — not a formal named middah of the 13
The Gemara uses this passuk in a sugya (proof, illustration, or dispute). Named as one of R' Yishmael’s 13 or R' Eliezer’s 32 only when that move is explicit.
Token drops are not a refutation of drought; the verse speaks of a real stopping of the heavens’ gift.
