A poor man needs a loan. He owns nothing he can offer as security except the coat on his back, so he hands the coat to the lender and takes the money. This was ordinary practice in the ancient world. It is how credit worked before there were banks, and the Bible permits it.
Then the Bible says this:
Look closely at that last line. The Hebrew word translated here as merit is tzedakah. God has just told the lender to give the coat back. That is a command, and the lender has no choice about it. But God does not describe the man’s obedience the way we would expect. He does not say the lender has followed the rules, or met his obligation, or done what the law requires. He says the act will be counted to him as tzedakah.
Tzedakah is the word Jews have used for centuries to mean charity. It is the coin dropped in the poor box. It is the gift you give to a man who has no claim on you whatsoever. That is a peculiar name for handing back collateral that you were ordered to hand back.
And the borrower’s reaction is stranger still. He blesses the lender. Nobody blesses a man for meeting a deadline in a contract.
So which is it? Is giving the coat back something the lender owes, or something he gives?
The answer is that this is a false choice, and the reason we struggle to see it is that we are reading in English.
Two things go wrong in translation. The first is that our English Bibles cover several different Hebrew words with the same handful of English ones. Tzedek and mishpat both routinely arrive as “justice,” and tzedakah shows up as “justice,” “righteousness,” or “charity,” depending on the verse and the translator. The reader in English has no way of knowing which Hebrew word he is actually looking at.
The second problem is deeper, and it is in our heads rather than on the page. In English, justice and charity are near opposites. Justice is what a man has coming to him. Charity is what he receives precisely because he has nothing coming to him. We keep those two ideas in separate rooms, and we are rather proud of the wall between them.
Biblical Hebrew tears the wall down. It has several distinct words for doing what is right, it uses them with great precision, and one of them refuses to sit on either side of our divide.
Two of these words carry the book of Deuteronomy, and Moses puts both of them into a single sentence.
Moses is at the end of his life, delivering his final address to the nation. He begins by remembering the day he appointed judges over Israel, and he repeats the charge he gave them:
Where our translations say “decide justly,” the Hebrew is more interesting. It reads, literally, “you shall judge tzedek.” The verb Moses uses for “judge” comes from the root of the Hebrew word mishpat. The word he attaches to it is tzedek. He has taken both of Hebrew’s great words for justice and welded them into one command.
He would not have done that if they meant the same thing. So what is the difference?
Mishpat is law. It is the verdict, the rule applied, the statute read correctly and enforced.
The heart of mishpat is impartiality, and that is exactly what Moses demands of his judges. Listen equally to the great man and the small one. Treat the citizen and the foreigner alike. Do not be intimidated by anyone.
This is justice with its eyes closed, and that is its glory, not its defect. A society where a poor man and a powerful man walk into the same courtroom and walk out with the same ruling is a rare thing in human history. Rabbi Jonathan Sacks put it beautifully: equality before the law is the translation into human terms of equality before God. That is why Moses anchors the whole system where he does. Judgment belongs to God, which is precisely why no judge is permitted to adjust it to please the man standing in front of him.
Tzedek is a wider word. It carries justice, righteousness, integrity, fairness, and charity all at once, which is why no single English word can hold it.
And the Bible teaches us what it means not by defining it but by showing it, which brings us back to the coat.
The lender is holding property he took in good faith. The borrower gave it to him freely. No court on earth would order a man to return his security every night at sundown and collect it again every morning, and God does not ask any court to do so. Instead He speaks past the courtroom, directly to the man holding the coat, and tells him that what the deal allows and what he ought to do are two different things.
That gap is tzedek. And look at how the same law is written in Exodus:
Same coat. Same deadline. Same command. But here God does not call it tzedakah at all. He ends the verse with the Hebrew words ki chanun ani, “for I am compassionate.” Deuteronomy calls the act righteousness, and Exodus calls it an imitation of God’s own kindness.
Set the two verses side by side and the conclusion is unavoidable. Whatever tzedakah means in Deuteronomy, it cannot simply mean obeying the law, because Exodus describes the identical act as an act of grace or compassion. Notice, too, how Exodus argues. It does not appeal to legal principle. It asks the question any decent person would ask if he were standing in the room: what else does the man have to sleep in?
At this point the conclusion seems obvious. Mishpat is the cold law and tzedek is the warm heart that softens it, and God wants us to follow the heart.
But that is not what the Bible says. Watch what happens when tzedek itself walks into a courtroom:
Do not pervert justice. Do not show favor to the poor or deference to the great. Judge your neighbor with tzedek. (Leviticus 19:15)
The same verse that commands tzedek forbids a judge from tilting his ruling toward a poor litigant out of sympathy. That is not compassion. It is corruption, and it happens to be the kind of corruption that kindhearted people are most likely to commit. As Sacks warned, without justice, love corrupts, because who among us would not bend the rules, if he could, to help the people he loves?
So tzedek is not softness, and it is not the opposite of law. It is the larger thing. Justice is already inside it, which is why you cannot arrive at tzedek by pitying the man in front of you, and compassion is inside it too, which is why you cannot arrive at tzedek merely by winning the argument. Sacks put the whole matter in a single equation: justice plus compassion equals tzedek.
The Sages tell a story that drives this home.
A wealthy scholar named Rabbah bar bar Chanan hired porters to move a barrel of wine, and they broke it. To cover his loss, he took their coats. The porters, now with no wages and no coats, went to a judge named Rav.
Rav told Rabbah to give the coats back.
“Is that the law?” Rabbah demanded.
Rav answered by quoting half a verse from Proverbs: so that you may walk in the way of good men.
Rabbah handed back the coats, and then the porters spoke up again. We are poor, they said. We worked all day. We are hungry and we have nothing.
Rav told Rabbah to pay their wages too.
“Is that the law?” Rabbah asked again. And Rav finished the verse: and keep the paths of the righteous.
Twice Rabbah asks about the law. Twice he is answered with something larger than the law, and the word Rav leaves him with, tzaddikim, the righteous, is built from the same root as tzedek. Rabbah wanted to know where he stood. Rav was telling him that a man can be standing exactly where justice tells him to stand and still be in the wrong place.
Justice without compassion produces a society that is perfectly lawful and quietly cruel. Compassion without justice produces a society whose rulings follow sympathy, which in practice means they follow whoever tells the most moving story. Neither one is enough on its own. Together, they are tzedek, righteousness, the prerequisite for a healthy society.
Which is why the word will not leave Deuteronomy alone. Moses is briefing the nation on the verge of sovereignty. They are about to cross a river into a land where they will plant and lend and build, where a man will hold his neighbor’s collateral at sundown, and where there will be no Moses to consult. So he tells them what the whole enterprise depends on. “Tzedek tzedek tirdof“, pursue tzedek, chase it down, “so that you may live and possess the land that the Lord your God is giving you” (Deuteronomy 16:20). Not merely so that you may be good, but so that you may keep the land. A nation can hold territory by force. The nation of Israel can only deserve its land by tzedek.
