'Righteous' in the Bible

Also -- when wicked men have slain the righteous man in his own house, on his bed; and now, do not I require his blood of your hand, and have taken you away from the earth?'

And Absalom saith, 'Who doth make me a judge in the land, that unto me doth come every man who hath a plea and judgment? -- then I have declared him righteous.'

He said -- the God of Israel -- to me, He spake -- the Rock of Israel: He who is ruling over man is righteous, He is ruling in the fear of God.
