'Free' in the Bible

There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus.

But Jerusalem which is above is free, which is the mother of us all.

So then, brethren, we are not children of the bondwoman, but of the free.

Stand fast therefore in the liberty wherewith Christ hath made us free, and be not entangled again with the yoke of bondage.
