Verse 19 He went and preached; an emphatical mode of expression, common in the Hebrew language, meaning he preached. So, in Acts 1:1, "all that Jesus began both to do and teach," means merely all that Jesus did and taught; and in Matthew 9:13, "Go ye and learn," &c., means, simply, learn.-- Unto the spirits in prison; that is, perhaps to mankind, in their state of guilt and condemnation. See Isaiah 42:7 , where the lost and helpless condition of men is represented as an imprisonment from which the gospel brings release. The meaning seems to be, that Jesus Christ, after suffering death, rose again by the power of the Spirit, and by the same Spirit brought the offers of pardon to mankind, who were under sentence of condemnation by the divine law; in consequence of which, as the writer goes on to explain in the Peter 3:20,21 a few are now saved, through baptism, just as in ancient times, in consequence of the preaching of Noah, a few were saved by the ark. Some suppose that the preaching here spoken of refers not to the general proclamation of the gospel to mankind, but to the warnings given by Noah to his generation, which they consider this passage as showing were inspired by Christ. Others suppose that this passage means that, during the interval between the Savior's death and his resurrection, he made the offers of salvation to departed spirits in the invisible world. The interpretation first given appears best to accord with the design of the writer in his remarks. In fact, the latter would seem to detach the passage entirely from its connection with what precedes and follows it. Besides, it is impossible to give any reason, if Jesus offered salvation to any departed spirits, why, of all the generations of the dead, the contemporaries of Noah alone were preached to in their prison.
