Charles Ellicott Commentary Luke 9:44-45

"Let these words sink into your ears: for the Son of man shall be delivered up into the hands of men. But they understood not this saying, and it was concealed from them, that they should not perceive it; and they were afraid to ask him about this saying." — Luke 9:44-45 (ASV)

Let these sayings sink down.—See Notes on Matthew 17:22-23, and Mark 9:30-32. Literally, Set these sayings in your ears; but the English version is quite adequate as an idiomatic rendering.

Shall be delivered.—Literally, is about to be delivered.
