'Guarded' in the Bible

On the night before Herod was to bring him out for execution, Peter, bound with two chains, was sleeping between two soldiers, while the sentries in front of the door guarded the prison.

After they had inflicted many blows on them, they threw them in jail, ordering the jailer to keep them securely guarded.

And when the blood of Your witness Stephen was being shed, I was standing by and approving, and I guarded the clothes of those who killed him.’

When we entered Rome, Paul was permitted to stay by himself with the soldier who guarded him.
