ἀσύνετος

Matthew 15:16 And Jesus said, Are ye also yet without understanding? Mark 7:18 And he saith unto them, Are ye so without understanding also? Do ye not perceive, that whatsoever thing from without entereth into the man, it cannot defile him; Romans 1:21 Because that, when they knew God, they glorified him not as God, neither were thankful; but became vain in their imaginations, and their foolish heart was darkened. Romans 1:31 Without understanding, covenant breakers, without natural affection, implacable, unmerciful: Romans 10:19 But I say, Did not Israel know? First Moses saith, I will provoke you to jealousy by them that are no people, and by a foolish nation I will anger you.
