David built there an altar to the LORD, and offered burnt offerings and shalom offerings. So the LORD was entreated for the land, and the plague was stayed from Yisra'el.
Aharon took as Moshe spoke, and ran into the midst of the assembly; and behold, the plague was begun among the people: and he put on the incense, and made atonement for the people.
Confess your offenses to one another, and pray for one another, that you may be healed. The insistent prayer of a righteous person is powerfully effective.
