'Free' in the Bible

I give praise to God, whose servant I have been, with a heart free from sin, from the time of my fathers, because in my prayers at all times the thought of you is with me, night and day

A fighting man, when he is with the army, keeps himself free from the business of this life so that he may be pleasing to him who has taken him into his army.

And so they may get themselves free from the net of the Evil One, being made the prisoners of the Lord's servant, for the purpose of God.

My punishments and pain; the things which came to me at Antioch, at Iconium, at Lystra; the cruel attacks made on me: and the Lord made me free from them all.
