And it was revealed unto him by the Holy Ghost, that he should not see death, before he had seen the Lord's Christ. It was revealed unto him - He was divinely informed, κεχρηματισμενον - he had an express communication from God concerning the subject. The secret of the Lord is with them that fear him. The soul of a righteous and devout man is a proper habitation for the Holy Spirit.
He should not see death - They that seek shall find: it is impossible that a man who is earnestly seeking the salvation of God, should be permitted to die without finding it.
The Lord's Christ - Rather, the Lord's anointed. That prophet, priest, and king, who was typified by so many anointed persons under the old covenant; and who was appointed to come in the fullness of time, to accomplish all that was written in the law, in the prophets, and in the Psalms, concerning him. See the note on Luke 2:11.
