And [after they] had inflicted many blows on them, they threw [them] into prison, giving orders to the jailer to guard them securely.

Be on guard for yourselves and for all the flock among which the Holy Spirit has appointed you [as] overseers, to shepherd the church of God which he obtained through the blood of his own [Son].

But [when] Paul appealed [that] he be kept under guard for the decision of His Majesty the Emperor, I gave orders [for] him to be kept under guard until I could send him to Caesar."
