'Right' in the Bible

When they saw the grace which was given to me, James and Cephas and John, who had the name of being pillars, gave to me and Barnabas their right hands as friends so that we might go to the Gentiles, and they to the circumcision;

And if you are Christ's, then you are Abraham's seed, and yours is the heritage by the right of God's undertaking given to Abraham.

But at that time, having no knowledge of God, you were servants to those who by right are no gods:

Brothers, if a man is taken in any wrongdoing, you who are of the Spirit will put such a one right in a spirit of love; keeping watch on yourself, for fear that you yourself may be tested.

And let us not get tired of well-doing; for at the right time we will get in the grain, if we do not give way to weariness.
