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).

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.
