What is scapegoat literary device?

The Word scapegoat turns out to be a mistranslation of the Hebrew Word 'azazel'. It was incorrectly transliterated into 'ez ozel', literally, 'the goat that departs'. In the Hebrew scriptures there is a tradition described in which a tribe forces a goat out into the wild, the idea being that the goat carries with it the sins and guilt of the people. The allusion carries through to the Greek Scriptures in which Christ is portrayed as the ultimate scapegoat, the innocent one who bears the iniquities of all.
