Numbers 16:48; Numbers 16:50; Numbers 25:8

48 He took his stand between the dead and the living, so that the plague was checked.
50 Then Aaron returned to Moses at the doorway of the tent of meeting, for the plague had been checked.
8 and he went after the man of Israel into the tent and pierced both of them through, the man of Israel and the woman, through the body. So the plague on the sons of Israel was checked.
