'Washed' in the Bible

Then David got up from the ground, washed, anointed himself [with olive oil], changed his clothes, and went into the house of the Lord and worshiped. Then he came [back] to his own house, and when he asked, they set food before him and he ate.

Then Mephibosheth the [grand]son of Saul came down to meet the king, but he had not cared for his feet, nor trimmed his mustache, nor washed his clothes from the day the king left until the day he returned in peace and safety.
