Then David built there an altar to Yahweh and offered burnt offerings and peace offerings. Thus Yahweh was moved by the entreaty for the land, and the plague was checked from being upon Israel.
So they each took his own censer and put fire on it, and laid incense on it; and they stood at the doorway of the tent of meeting, with Moses and Aaron.
Then Aaron took it as Moses had spoken, and ran into the midst of the assembly, for behold, the plague had begun among the people. So he put on the incense and made atonement for the people.
Therefore, confess your sins to one another, and pray for one another so that you may be healed. The effective prayer of a righteous man can accomplish much.
