Hygiene

If there be among you any man, that is not clean by reason of uncleanness that chanceth him by night, then shall he go abroad out of the camp, he shall not come within the camp:

But it shall be, when evening cometh on, he shall wash himself with water: and when the sun is down, he shall come into the camp again.

Woe unto you, scribes and Pharisees, hypocrites! for ye make clean the outside of the cup and of the platter, but within they are full of extortion and excess.

Thou blind Pharisee, cleanse first that which is within the cup and platter, that the outside of them may be clean also.
