The Jews (oi Ioudaioi). Probably the incredulous and hostile section of the Pharisees in verse Matthew 16 (cf. Matthew 5:10 ). Did not believe (ouk episteusan). The facts told by the man, "that he had been blind and had received his sight" (oti hn tuplo kai aneblepsen), conflicted with their theological views of God and the Sabbath. So they refused belief "until they called the parents" (ew otou epwnhsan tou gonei). Usual construction of ew otou ( = until which time, like ew alone) with aorist active indicative of pwnew, old verb from pwnh (voice, sound). They called out loud for his parents to throw light on this grave problem to cover up their own stupidity.
