'Righteousness' in the Bible

And Jesus answering said unto him, Suffer it to be so now: for thus it becometh us to fulfil all righteousness. Then he suffered him.

Blessed are they which do hunger and thirst after righteousness: for they shall be filled.

Blessed are they which are persecuted for righteousness' sake: for theirs is the kingdom of heaven.

For I say unto you, That except your righteousness shall exceed the righteousness of the scribes and Pharisees, ye shall in no case enter into the kingdom of heaven.

But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you.

For John came unto you in the way of righteousness, and ye believed him not: but the publicans and the harlots believed him: and ye, when ye had seen it, repented not afterward, that ye might believe him.
