'Washed' in the Bible

Then David arose from the earth, and washed, and anointed himself, and changed his clothing; and he came into the house of Yahweh, and worshiped: then he came to his own house; and when he required, they set bread before him, and he ate.

Mephibosheth the son of Saul came down to meet the king; and he had neither groomed his feet, nor trimmed his beard, nor washed his clothes, from the day the king departed until the day he came home in peace.
