Luke 24:25

He said to them, "So you do not understand, either? Do you not see how nothing outside a man can defile him by entering him?

He noted this and said to them, "Why do you argue you have no bread? Do you not see, do you not understand, even yet? Are you still dull of heart?

He answered them, "O faithless generation, how long must I still be with you? how long have I to bear with you? Bring him to me."

Afterwards he appeared at table to the eleven themselves and reproached them for their unbelief and dulness of mind, because they had not believed those who saw him risen from the dead. [But they excused themselves, saying, "This age of lawlessness and unbelief lies under the sway of Satan, who will not allow what lies under the unclean spirits to understand the truth and power of God; therefore," they said to Christ, "reveal your righteousness now." Christ answered them, "The term of years for Satan's power has now expired, but other terrors are at hand. I was delivered to death on behalf of sinners, that they might return to the truth and sin no more, that they might inherit that glory of righteousness which is spiritual and imperishable in heaven."]

On this point I have a great deal to say, which it is hard to make intelligible to you. For you have grown dull of hearing.

Only, how could the scriptures be fulfilled then ??the scriptures that say this must be so?"

He said to them, "So you do not understand, either? Do you not see how nothing outside a man can defile him by entering him?

However, they did not understand a word of this; indeed the saying was hidden from them, and they did not know what he meant.
