A number of times in the Word the Law is summarized. Some of them equate the Law to the fear of the Lord through the treatment of the widow and orphan and the proliferation of sorcery (probably connected with the use of drugs), adultery, oppression of the hired worker by stealing his wages (like our government) and those who swear falsely (such as politicians who take the oath of office to defend the Constitution and do not).
“Then I will draw near to you for judgment. I will be a swift witness against the sorcerers, against the adulterers, against those who swear falsely, against those who oppress the hired worker in his wages, the widow and the fatherless, against those who thrust aside the sojourner, and do not fear me, says the LORD of hosts. (Malachi 3:5, ESV)
Some equate justice and righteousness to the treatment of the widow and orphan or the shedding of innocent blood (think of Benghazi, abortion or the Gosnell murders).
Thus says the LORD: Do justice and righteousness, and deliver from the hand of the oppressor him who has been robbed. And do no wrong or violence to the resident alien, the fatherless, and the widow, nor shed innocent blood in this place. (Jeremiah 22:3, ESV)
And some are more comprehensive, covering what is “just and right” whether it is ceremonial, civil or moral.
“If a man is righteous and does what is just and right— if he does not eat upon the mountains or lift up his eyes to the idols of the house of Israel, does not defile his neighbor’s wife or approach a woman in her time of menstrual impurity, does not oppress anyone, but restores to the debtor his pledge, commits no robbery, gives his bread to the hungry and covers the naked with a garment, does not lend at interest or take any profit, withholds his hand from injustice, executes true justice between man and man, walks in my statutes, and keeps my rules by acting faithfully—he is righteous; he shall surely live, declares the Lord GOD. (Ezekiel 18:5–9, ESV)
But His statutes and rules by any measure are the definition of justice and righteousness.
For truly, I say to you, until heaven and earth pass away, not an iota, not a dot, will pass from the Law until all is accomplished. Therefore whoever relaxes one of the least of these commandments and teaches others to do the same will be called least in the kingdom of heaven, but whoever does them and teaches them will be called great in the kingdom of heaven. (Matthew 5:18–19, ESV)
