Janus Parallelism. This type of parallelism hinges on the use of a single word with two different meanings, one of which forms a parallel with what precedes and the other with what follows. Thus, by virtue of a double entendre, the parallelism faces in both directions. Berlin, A. (1992). Parallelism. In D. N. Freedman (Ed.), The Anchor Yale Bible Dictionary (Vol. 5, p. 157). New York: Doubleday.
Awareness of Janus Parallelism was lost until Hebrew expert Cyrus Gordon rediscovered them in 1978 (New Directions, BASP 15, pp. 59-60). The apostles Matthew and John, experts in Hebrew Scripture would be very familiar with them.
