Matthew 16:7

They reasoned (dielogizonto). It was pathetic, the almost jejune inability of the disciples to understand the parabolic warning against "the leaven of the Pharisees and Sadducees" (verse Mark 6 ) after the collision of Christ just before with both parties in Magadan. They kept it up, imperfect tense. It is "loaves" (artou) rather than "bread."
