Both one (ta ampotera en). "The both" (Jew and Gentile). Jesus had said "other sheep I have which are not of this fold" ( John 10:16 ).

Brake down the middle wall of partition (to mesotoicon tou pragmou lusa). "Having loosened (first aorist active participle of luw, see John 2:19 ) the middle-wall (late word, only here in N.T., and very rare anywhere, one in papyri, and one inscription) of partition (pragmou, old word, fence, from prassw, to fence or hedge, as in Matthew 21:33 )." In the temple courts a partition wall divided the court of the Gentiles from the court of Israel with an inscription forbidding a Gentile from going further (Josephus, Ant. VIII. 3, 2). See the uproar when Paul was accused of taking Trophimus beyond this wall ( Acts 21:28 ).
