This expression occurs in two places only: in Matt. 19:28, when it refers to the new order of things, when the Son of man will reign in the millennium; and in Titus 3:5, to the new birth, as in John 3, by the word and spirit. It is called “washing,” because this new birth is a moral and inward cleansing of the entire man by the imparting of a new life. This is the force of washed or bathed in John 13:10. “He that is washed.” Among Christians “regeneration” is a common expression for the new birth, though it is worthy of notice that the word for this is different.
