And the LORD said unto Moses, Speak unto the priests the sons of Aaron, and say unto them, There shall none defile himself for the dead among his people:
And you must abide outside the camp seven days: whosoever has killed any person, and whosoever has touched any slain, purify both yourselves and your captives on the third day, and on the seventh day.
And there were certain men, who were defiled by the dead body of a man, that they could not keep the passover on that day: and they came before Moses and before Aaron on that day:
Woe unto you, scribes and Pharisees, hypocrites! for you are like unto whitewashed sepulchers, which indeed appear beautiful outwardly but are within full of dead men's bones, and of all uncleanness.
