'Rightly' in the Bible

And he said, Is not he rightly named Jacob? for he hath supplanted me these two times: he took away my birthright; and, behold, now he hath taken away my blessing. And he said, Hast thou not reserved a blessing for me?

Simon answered and said, I suppose that he, to whom he forgave most. And he said unto him, Thou hast rightly judged.

And they asked him, saying, Master, we know that thou sayest and teachest rightly, neither acceptest thou the person of any, but teachest the way of God truly:

Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.
