Luke 9:44-45

⁴⁴And all were astonished at the mighty power of God. But while all wondered at all the things he did, he said to his disciples: Lay you up in your hearts these words, for it shall come to pass, that the Son of man shall be delivered into the hands of men.

⁴⁵But they understood not this word; and it was hid from them, so that they perceived it not. And they were afraid to ask him concerning this word.
