As they were speaking to the people, the priests and the captain of the temple guard and the Sadducees came up to them,

Now when the captain of the temple guard and the chief priests heard these words, they were greatly perplexed about them as to what would come of this.

When he had seized him, he put him in prison, delivering him to four squads of soldiers to guard him, intending after the Passover to bring him out before the people.

When they had passed the first and second guard, they came to the iron gate that leads into the city, which opened for them by itself; and they went out and went along one street, and immediately the angel departed from him.

When they had struck them with many blows, they threw them into prison, commanding the jailer to guard them securely;

Be on guard for yourselves and for all the flock, among which the Holy Spirit has made you overseers, to shepherd the church of God which He purchased with His own blood.
