Acts 12:17

He went into another place. Did not think fit to stay in the city of Jerusalem. St. John Chrysostom takes notice, that upon another occasion, when he was delivered by an Angel out of prison, he went boldly the next day, and preached in the temple. (chap. v. 19.) but there he was ordered by an Angel so to do; now to stay without such orders, would have been rashly to expose himself, and in a manner tempting God. (Witham) --- Peter retired to another place, that he might not rashly expose himself to future danger. It is not just to depend on supernatural assistance, when human means are adequate to the effect. (St. John Chrysostom, hom. xxvi.) --- St. Peter desires they will announce his miraculous deliverance to James, the then bishop of Jerusalem, and to the Christians, that they might see the effect of their prayers for him. St. James had, beyond a doubt, ordered general supplications to be made by all the brethren for St. Peter. (Bristow)
