(in the spelling of this word h is inserted by mistake from Latin MSS.), rather Cleopas, which is the Greek form of the word, while Clopas is the Aramaic form. In John 19:25 the Authorized Version reads, "Mary, the wife of Clopas." The word "wife" is conjecturally inserted here. If "wife" is rightly inserted, then Mary was the mother of James the Less, and Clopas is the same as Alphaeus (Matthew 10:3; 27:56).

klo'-pas (Klopas): The former in the Revised Version (British and American), the latter in the King James Version, of John 19:25, for the name of the husband of one of the women who stood by the cross of Christ. Upon the philological ground of a variety in pronunciation of the Hebrew root, sometimes identified with Alpheus, the father of James the Less. Said by tradition to have been the brother of Joseph, the husband of Mary; see BRETHREN OF THE LORD. Distinguished from Cleopas, a Greek word, while Clopas is Aramaic
