“Having called one of the centurions.” In order not to spread the matter abroad, and to keep it as secret as possible, the apostle does not tell the centurion about it. Instead, he asks that his nephew be taken directly to the tribune.
Thus only three knew of the plot against his life: Paul himself, his nephew, and the tribune (v. 22).
“It is worthy of wonder,” says Chrysostom, “how Paul was not troubled when he heard of the plot against him. He did not say, ‘What does this mean? Is what Christ told me true?’ (v. 11). No, he neither thought nor felt anything of the kind, but only believed. Yet while believing, he did not sleep. He did not fail to do what could be done with the help of human wisdom.”
“He took him by the hand,” that is, in a friendly manner, and withdrew aside, so that no one would hear and the secret would be preserved.
