'Washed' in the Bible

At this, David got up from the ground, washed, anointed himself, changed his clothes, and went into the LORD's tent to worship. Then he went back to his palace where, at his request, they served him food and he ate.

Meanwhile, Saul's grandson Mephibosheth also went out to greet 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.
