'Righteous' in the Bible

These are the generations of Noah. Noah was a righteous man, and perfect in his generations: Noah walked with God.

And Jehovah said unto Noah, Come thou and all thy house into the ark; for thee have I seen righteous before me in this generation.

And Abraham drew near, and said, Wilt thou consume the righteous with the wicked?

Peradventure there are fifty righteous within the city: wilt thou consume and not spare the place for the fifty righteous that are therein?

That be far from thee to do after this manner, to slay the righteous with the wicked, that so the righteous should be as the wicked; that be far from thee: shall not the Judge of all the earth do right?

And Jehovah said, If I find in Sodom fifty righteous within the city, then I will spare all the place for their sake.

peradventure there shall lack five of the fifty righteous: wilt thou destroy all the city for lack of five? And he said, I will not destroy it, if I find there forty and five.

Now Abimelech had not come near her. And he said, Lord, wilt thou slay even a righteous nation?

And Judah acknowledged them, and said, She is more righteous than I; forasmuch as I gave her not to Shelah my son. And he knew her again no more.
