Luke 9:43 Meaning and Commentary

Luke 9:43

And they were all amazed at the mighty power of God
Or at "the greatness", or "majesty of God"; which was displayed in this cure: for the great power of God was manifestly seen in it, to the astonishment of the disciples, who could not cure this child, and of the parent and friends of it, and of the whole multitude: and to the confusion of the Scribes and Pharisees:

but while they wondered every one, at all things which Jesus did;
and were applauding him for them, and speaking in his praise on account of them:

he said unto his disciples;
privately, when they were alone together, the following words, that he might not seem to be lifted up with the praise of men; and also to show their inconstancy, that those who, now admired him, would one day crucify him; and to take off the thoughts of the disciples from a temporal kingdom and glory, they were so much in expectation of, and which every miracle of Christ, and the applause he got thereby among men, strengthened them in.

Luke 9:43 In-Context

41 And Jesus said, O generation without faith and false in heart, how long will I have to be with you and put up with you? let your son come here.

42 And while he was coming, he was pushed violently down and twisted by the evil spirit. But Jesus gave sharp orders to the unclean spirit, and made the boy well, and gave him back to his father.

43 And they were full of wonder at the great power of God. But while they were all wondering at all the things which he did, he said to his disciples,

44 Let these words go deep into your ears, for the Son of man will be given up into the hands of men.

45 But this saying was not clear to them and its sense was kept secret from them so that they were not able to see it: and they had fear of questioning him about it.
