'Free' in the Bible

"If you had known God's free gift," replied Jesus, "and who it is that said to you, 'Give me some water,' you would have asked Him, and He would have given you living water."

and you shall know the Truth, and the Truth will make you free."

"We are descendants of Abraham," they answered, "and have never at any time been in slavery to any one. What do those words of yours mean, 'You shall become free'?"

If then the Son shall make you free, you will be free indeed.

The dead man came out, his hands and feet wrapped in cloths, and his face wrapped round with a towel. "Untie him," said Jesus, "and let him go free."
