'Captain' in the Bible

As they spoke to the people, the priests and the captain of the temple and the Sadducees came to them,

Now when the high priest, the captain of the temple, and the chief priests heard these words, they were very perplexed about them and what might become of this.

Then the captain went with the officers, and brought them without violence, for they were afraid that the people might stone them.

Immediately he took soldiers and centurions, and ran down to them. They, when they saw the chief captain and the soldiers, stopped beating Paul.

When we entered into Rome, the centurion delivered the prisoners to the captain of the guard, but Paul was allowed to stay by himself with the soldier who guarded him.
