'Unharmed' in the Bible

When a man finds his enemy, does he let him go unharmed? May the Lord repay you with good for what you’ve done for me today.

God is wise and all-powerful.Who has opposed Him and come out unharmed?

Though many are against me,He will redeem me from my battle unharmed.

He exclaimed, “Look! I see four men, not tied, walking around in the fire unharmed; and the fourth looks like a son of the gods.”
