Commentary for II Kings 3:20

At the time of the morning when the meal-offering was brought up. The water began falling from heaven in the morning¹⁴Rashi is explaining the apparent contradiction between the expressions “morning” and “when the meal-offering was offered up” which refers to the afternoon services. Rashi explains that two expressions refer to the beginning and end of the miracle. in the land of Edom,¹⁵Alternatively, God caused one of the rivers in Edom to overflow its banks causing the valley near the camp to fill with water.—Radak and at the [time of] offering up the meal-offering, it came surging into that valley, because Elisha had said, “You will not see wind and you will not see rain.”¹⁶Above v. 17. [This is stated] in the Midrash of Rabbi Tanchuma.
