The sacred writer seems to have had in view the Lord's descent on Mount Sinai, at the giving of the law. But surely we can discover that what he here delivered was under the spirit of prophecy, in reference to the triumphs of Jesus at his resurrection. Then the earthquake, and the other prodigies of that hour, testified the Lord's displeasure at sin, and his perfect approbation of the redemption by Jesus, in raising him from the dead. Matthew 28:2.
