Matthew 15:16

ἀκμὴν, accusative of ἀκμή, the point (of a weapon, etc.) = κατʼ ἀκμὴν χρόνου, at this point of time, still; late Greek, and condemned by Phryn., p. 123 (ἀντὶ τοῦ ἔτι). ἀσύνετοί ἐστε. Christ chides the Twelve for making a mystery of a plain matter (“quare parabolice dictum putet quod perspicue locutus est,” Jerome). Very simple and axiomatic to the Master, but was it ever quite clear to the disciples? In such matters all depends on possessing the requisite spiritual sense. Easy to see when you have eyes.
