'Righteousness' in the Bible

But Jesus answering said unto him, Suffer it now: for thus it becometh us to fulfil all righteousness. Then he suffereth him.

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

Blessed are they that have been 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 wise enter into the kingdom of heaven.

Take heed that ye do not your righteousness before men, to be seen of them: else ye have no reward with your Father who is in heaven.

But seek ye first his kingdom, 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 saw it, did not even repent yourselves afterward, that ye might believe him.
