And encamp ye without the camp seven days: whosoever hath killed any person, and whosoever hath touched any slain, purify yourselves on the third day and on the seventh day, ye and your captives.
And there were certain men, who were unclean by the dead body of a man, so 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 ye are like unto whited sepulchres, which outwardly appear beautiful, but inwardly are full of dead men's bones, and of all uncleanness.
