What is "clopas"

Clopas (Greek Klopas Κλωπᾶς; Hebrew possibly חלפי (Halfi); Aramaic חילפאי (Hilfài), is a figure of early Christianity. The name appears only once in the New Testament, specifically in John 19:25: He is often identified with another figure of a similar name, Cleopas (Κλεοπᾶς), one of the two disciples who met Christ during the road to Emmaus appearance . There is some variation of the Greek manuscripts in both John 19:25 and Luke 24 as to the spelling Κλ[ε]οπᾶς, and the John "Clopas" is rendered "Cleophas" in the KJV.
