'Safe' in the Bible

When a strong man, fully armed, guards his own palace, his possessions are safe.

The slave replied, 'Your brother has returned, and your father has killed the fattened calf because he got his son back safe and sound.'

I am no longer in the world, but they are in the world, and I am coming to you. Holy Father, keep them safe in your name that you have given me, so that they may be one just as we are one.

When I was with them I kept them safe and watched over them in your name that you have given me. Not one of them was lost except the one destined for destruction, so that the scripture could be fulfilled.

I am not asking you to take them out of the world, but that you keep them safe from the evil one.
