Bamidbar 11:1-2

Orthodox Jewish Bible

11 And when the people complained, it displeased Hashem; Hashem heard it; His anger was kindled; and the Eish Hashem burned among them, and consumed them that were at the edge of the machaneh.

² And the people cried unto Moshe; and when Moshe davened unto Hashem, the eish was quenched.
