'Righteousness' in the Bible

And he believed in Jehovah; and he reckoned it to him for righteousness.

For I have known him, to the end that he may command his children and his household after him, that they may keep the way of Jehovah, to do righteousness and justice; to the end that Jehovah may bring upon Abraham that which he hath spoken of him.

So shall my righteousness answer for me hereafter, when thou shalt come concerning my hire that is before thee: every one that is not speckled and spotted among the goats, and black among the sheep, that if found with me, shall be counted stolen.
