'Free' in the Bible

Hast thou been called being a bondman, let it not concern thee; but and if thou canst become free, use it rather.

Art thou bound to a wife? seek not to be loosed; art thou free from a wife? do not seek a wife.

A wife is bound for whatever time her husband lives; but if the husband be fallen asleep, she is free to be married to whom she will, only in the Lord.

Am I not free? am I not an apostle? have I not seen Jesus our Lord? are not ye my work in the Lord?

For being free from all, I have made myself bondman to all, that I might gain the most possible.

For also in the power of one Spirit we have all been baptised into one body, whether Jews or Greeks, whether bondmen or free, and have all been given to drink of one Spirit.
