'Righteous' in the Bible

These are the records of the generations (family history) of Noah. Noah was a righteous man [one who was just and had right standing with God], blameless in his [evil] generation; Noah walked (lived) [in habitual fellowship] with God.

Then the Lord said to Noah, “Come into the ark, you with all your household, for you [alone] I have seen as righteous (doing what is right) before Me in this generation.

For I have known (chosen, acknowledged) him [as My own], so that he may teach and command his children and [the sons of] his household after him to keep the way of the Lord by doing what is righteous and just, so that the Lord may bring upon Abraham what He has promised him.”

Abraham approached [the Lord] and said, “Will You really sweep away the righteous (those who do right) with the wicked (those who do evil)?

Suppose there are fifty righteous [people] within the city; will You really sweep it away and not spare it for the sake of the fifty righteous who are in it?

Far be it from You to do such a thing—to strike the righteous with the wicked, so that the righteous and the wicked are treated alike. Far be it from You! Shall not the Judge of all the earth do right [by executing just and righteous judgment]?”

So the Lord said, “If I find within the city of Sodom fifty righteous [people], then I will spare the entire place for their sake.”

If five of the fifty righteous are lacking, will You destroy the entire city for lack of five?” And He said, “If I find [at least] forty-five [righteous people] there, I will not destroy it.”

Then Abraham said, “Oh may the Lord not be angry [with me], and I will speak only this once; suppose ten [righteous people] are found there?” And He said, “I will not destroy it for the sake of the ten.”

Judah recognized the articles, and said, “She has been more righteous [in this matter] than I, because I did not give her to my son Shelah [as I had promised].” And Judah did not have [intimate] relations with her again.
