'Washing' in the Bible

And it came to pass in an eveningtide, that David arose from off his bed, and walked upon the roof of the king's house: and from the roof he saw a woman washing herself; and the woman was very beautiful to look upon.

Then David got up from the earth, and after washing and rubbing himself with oil and changing his clothing, he went into the house of the Lord and gave worship: then he went back to his house, and at his order they put food before him and he had a meal.
