The Bible talks about the righteous 568 times.  

Who are they?

“Yet the righteous will hold to his way, And he who has clean hands will be stronger and stronger.” Job 17:9

And then we see in Proverbs 4:18, “But the path of the just (righteous) is like the shining sun,
That shines ever brighter unto the perfect day.”

The righteous are those who are right in God’s sight and have a relationship with God.  They will live by faith; they will be radiant; they will grow in their spiritual life, getting stronger and stronger.  

“Blessed are those who hunger and thirst for righteousness, For they shall be filled.”  Mathew 5:6
