'Right' in the Bible

But as many as received him, to them gave he the right to become children of God, even to them that believe on his name:

Simon Peter therefore having a sword drew it, and struck the high priest's servant, and cut off his right ear. Now the servant's name was Malchus.

And he said unto them, Cast the net on the right side of the boat, and ye shall find. They cast therefore, and now they were not able to draw it for the multitude of fishes.
