'Righteousness' in the Bible

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

For I know him that he will command his children and his household after him, and they shall keep the way of Jehovah, to do righteousness and justice, in order that Jehovah may bring upon Abraham what he hath spoken of him.

And my righteousness shall answer for me hereafter, when thou comest about my hire, before thy face: all that is not speckled and spotted among the goats, and brown among the lambs, let that be stolen with me.
