'Washed' in the Bible

David stood up from the ground and washed and anointed himself and changed his clothing. Then he went [to] the house of Yahweh and worshiped, and he went to his [own] house. He asked, so they served him food, and he ate.

Now, Mephibosheth the son of Saul came down to meet the king; he had not taken care of his feet nor trimmed his moustache nor washed his clothes from the day the king left until the day he came back in peace.
