'Washed' in the Bible

Then David got up from the ground. He washed, anointed himself, changed his clothes, went to the Lord’s house, and worshiped. Then he went home and requested something to eat. So they served him food, and he ate.

Mephibosheth, Saul’s grandson, also went down to meet the king. He had not taken care of his feet, trimmed his mustache, or washed his clothes from the day the king left until the day he returned safely.
