'Guards' in the Bible

saying, "We found the prison locked with all security and the guards standing at the doors, but [when we] opened [them], we found no one inside!"

Now when Herod was about to bring him [out], on that [very] night Peter was sleeping between two soldiers, bound with two chains, and guards before the door were watching the prison.

And [when] Herod had searched for him and did not find [him], he questioned the guards [and] ordered [that they] be led away to execution. And he came down from Judea to Caesarea [and] stayed [there].
