'Keeper' in the Bible

And when they had given them a great number of blows, they put them in prison, giving orders to the keeper of the prison to keep them safely:

And the keeper, coming out of his sleep, and seeing the prison doors open, took his sword and was about to put himself to death, fearing that the prisoners had got away.

And the keeper said to Paul, The authorities have given orders to let you go: come out now, and go in peace.

And when the chief secretary had got the people quiet, he said, Men of Ephesus, is any man without knowledge that the town of Ephesus is the keeper of the holy place of the great Diana, who was sent down from Jupiter?
