'Guards' in the Bible

and I say to them, 'Let not the gates of Jerusalem be opened till the heat of the sun, and while they are standing by let them shut the doors, and fasten, and appoint guards of the inhabitants of Jerusalem, each in his guard, and each over-against his house.'

and when Herod was about to bring him forth, the same night was Peter sleeping between two soldiers, having been bound with two chains, guards also before the door were keeping the prison,

and Herod having sought for him, and not having found, having examined the guards, did command them to be led away to punishment, and having gone down from Judea to Caesarea, he was abiding there.
