The Hour of Minchah
Eliyahu was answered at Minchah, the hour of judgment, and in that same hour our own afternoon prayer breaks the forces that rise against us.
When Yaakov sent a gift, a minchah, to Esav, the Noam Elimelech hears in the word the afternoon prayer. Minchah, he teaches, is the hour when the dinim, the harsh judgments, grow strong. When a tzaddik must protect himself from a wicked man who has risen against him, he turns those judgments against his attacker. That is why Eliyahu took his vengeance on the prophets of the Baal at that very hour, and that was Yaakov's intent as well: to bring the judgments down on Esav so that he could do no harm. Earlier in the parsha the Rebbe recalls that Eliyahu was answered only in the Minchah prayer, and he adds that through our own Minchah, which we send up to Hashem, we break the judgments that seek to rule over us. The letters of minchah also spell menuchah, rest, and machaneh, camp: Yaakov's gift called down camps of angels to save him and grant him rest.

Minchah falls in the middle of the day's pressure, which is exactly why it is easy to rush or skip. Tomorrow, set a reminder on your phone fifteen minutes before Minchah time. When it rings, close what you are doing, step aside, and daven slowly, even if only the Shemoneh Esrei. If something or someone is weighing on you, name it quietly before Hashem in that prayer, the way Eliyahu did on the mountain.
