'Turning' in the Bible

See to it, my brothers, that no evil, unbelieving heart is found in any of you, as shown by your turning away from the living God.

For this reason let us go on from the first things about Christ to full growth; not building again that on which it is based, that is, the turning of the heart from dead works, and faith in God,

For this Melchisedek, king of Salem, priest of God Most High, who did meet Abraham turning back from the smiting of the kings, and did bless him,

And truly if they had kept in mind the country from which they went out, they would have had chances of turning back.
