'Righteousness' in the Bible

But Jesus answering said to him, 'Suffer now, for thus it is becoming to us to fulfil all righteousness,' then he doth suffer him.

Happy those hungering and thirsting for righteousness -- because they shall be filled.

Happy those persecuted for righteousness' sake -- because theirs is the reign of the heavens.

'For I say to you, that if your righteousness may not abound above that of the scribes and Pharisees, ye may not enter to the reign of the heavens.

but seek ye first the reign of God and His righteousness, and all these shall be added to you.

for John came unto you in the way of righteousness, and ye did not believe him, and the tax-gatherers and the harlots did believe him, and ye, having seen, repented not at last -- to believe him.
