'Safe' in the Bible

Then Jesus said to them, “I ask you directly: Is it lawful to do good on the Sabbath or to do evil, to save a life or to destroy it?”

"When a strong man, fully armed, guards his own mansion, his property is safe.

And he said unto him, Thy brother is come; and thy father hath killed the fatted calf, because he hath received him safe and sound.

Any man who makes it his object to keep his own life safe, will lose it; but whoever loses his life will preserve it.
