2 Samuel 19:24

And the king said to Semei, Thou shalt not die: and the king swore to him.

And Memphibosthe the son of Saul's son went down to meet the king, and had not dressed his feet, nor pared his nails, nor shaved himself, neither had he washed his garments, from the day that the king departed, until the day when he arrived in peace.

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.
