Acts 13:11

Verse 11. The hand of the Lord is upon thee. God shall punish thee. By this sudden and miraculous punishment, he would be awed and humbled; and the proconsul and others would be convinced that he was an impostor, and that the gospel was true. His wickedness deserved such a punishment; and at the same time that due punishment was inflicted, it was designed that the gospel should be extended by this means. In all this there was the highest evidence that Paul was under the inspiration of God. He was full of the Holy Ghost; he detected the secret feelings and desires of the heart of Elymas, and he inflicted on him a punishment that could have proceeded from none but God.
