In front of the tent and east of the Tent of Meeting, Moses, Aaron, and Aaron's sons encamped facing the east. They were tasked to perform the duties of the sanctuary and care for the needs of the Israelis. Any unauthorized person who approached was to be executed.

They executed the five kings of Midian, including Evi, Rekem, Zur, Hur, and Reba. They also executed Beor's son Balaam with a sword.

For the Egyptians buried all their firstborn, which the LORD had smitten among them: upon their gods also the LORD executed judgments.

"Every murderer of a human being is to be executed only according to testimony given by multiple witnesses. A single witness is not to result in a death sentence.
