3 verses in the King James Version. Word study for “righteousness” →
If ye know that he is righteous, ye know that every one that doeth righteousness is born of him.
Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous.
In this the children of God are manifest, and the children of the devil: whosoever doeth not righteousness is not of God, neither he that loveth not his brother.
