Matthew 13:15
Context13:15 For the heart of this people has become dull;
they are hard of hearing,
and they have shut their eyes,
so that they would not see with their eyes
and hear with their ears
and understand with their hearts
and turn, and I would heal them.’ 1
Matthew 21:19
Context21:19 After noticing a fig tree 2 by the road he went to it, but found nothing on it except leaves. He said to it, “Never again will there be fruit from you!” And the fig tree withered at once.
