555. Did the disciples understand when Jesus told them about his coming death?


Yes

And they were very sorry to hear it.
And while they abode in Galilee, Jesus said unto them, The Son of man shall be betrayed into the hands of men: And they shall kill him, and the third day he shall be raised again. And they were exceeding sorry. Matthew 17:22-23

No

But they were too afraid to ask him what he meant.
He taught his disciples, and said unto them, The Son of man is delivered into the hands of men, and they shall kill him; and after that he is killed, he shall rise the third day. But they understood not that saying, and were afraid to ask him. Mark 9:30-31

Let these sayings sink down into your ears: for the Son of man shall be delivered into the hands of men. But they understood not this saying, and it was hid from them, that they perceived it not: and they feared to ask him of that saying. Luke 9:44-45
