Justice, Justice Shalt Thou Pursue

צֶדֶק צֶדֶק תִּרְדֹּף
Source: Deuteronomy 16:20  ·  Maimonides, Sefer HaMitzvot, Positive #138

'That which is altogether just shalt thou follow' — in Hebrew, tzedek, tzedek tirdof, 'justice, justice shalt thou pursue.' Deuteronomy 16:20 closes the paragraph that began with #137's command to appoint judges 'in all thy gates,' adding something courts alone cannot guarantee: active pursuit. The structure itself traces back to Jethro's rebuke of Moses — 'The thing that thou doest is not good' (Exodus 18:17) — and forward to Jehoshaphat's judges, instructed not merely to rule on disputes but to 'warn' people before wrongdoing escalated (2 Chronicles 19:10).

Justice, Justice Shalt Thou Pursue

צֶדֶק צֶדֶק תִּרְדֹּף לְמַעַן תִּחְיֶה וְיָרַשְׁתָּ אֶת הָאָרֶץ אֲשֶׁר יְהוָה אֱלֹהֶיךָ נֹתֵן לָךְ
"That which is altogether just shalt thou follow, that thou mayest live, and inherit the land which the LORD thy God giveth thee."

In Hebrew the verse repeats its key word: tzedek, tzedek tirdof — "justice, justice shalt thou pursue." The KJV renders it "That which is altogether just shalt thou follow," but the doubling in the Hebrew is the point. This verse does not stand alone; it is the close of the same paragraph that gave #137 its commandment to appoint "judges and officers... in all thy gates" (Deuteronomy 16:18), and that, in the verse between them, forbids the judges themselves from wresting judgment, respecting persons, or taking a gift (Deuteronomy 16:19).

Read as one unit, the progression is exact: build the courts (16:18) — bind the judges inside them (16:19) — and then, having done both, still pursue justice (16:20), as though the first two steps were necessary but the third is the one that never finishes. A court can exist, and be honestly staffed, and justice can still fail to arrive at someone's door simply because no one went looking for where it was needed. "Pursue" is an active verb. Courts wait for cases to come to them. Pursuit goes the other direction.

The Thing That Thou Doest Is Not Good

The institution of #137 — judges "in all thy gates" — has an origin story, and it begins with Moses doing the opposite: sitting alone, all day, as every dispute in the camp came to him personally. Exodus 18:13 records the scene: "Moses sat to judge the people: and the people stood by Moses from morning unto even." His father-in-law Jethro, watching this, does not praise his diligence. "The thing that thou doest is not good", he says (Exodus 18:17) — one man cannot pursue justice for an entire nation by himself, no matter how willing he is.

Jethro's solution is structural: "thou shalt provide out of all the people able men, such as fear God, men of truth, hating covetousness; and place such over them, to be rulers of thousands... hundreds... fifties, and... tens" (Exodus 18:21). The result, in verse 26, is a justice system that can actually pursue: "they judged the people at all seasons: the hard causes they brought unto Moses, but every small matter they judged themselves" (Exodus 18:26). Deuteronomy 16:18's "judges in all thy gates" is Jethro's proposal, generations later, written into the law of the land — the structure that makes Deuteronomy 16:20's pursuit even possible.

Warn Them That They Trespass Not

What does "pursuing" justice look like once the structure exists? #137 already showed Jehoshaphat setting judges "city by city" (2 Chronicles 19:5). The instructions he gave them go further than simply telling them to rule honestly when a case arrives. 2 Chronicles 19:10 records Jehoshaphat telling the judges that whenever any dispute comes to them from the people in their cities, "ye shall even warn them that they trespass not against the LORD, and so wrath come upon you, and upon your brethren."

Warning is not waiting. A court that only rules on the cases brought to it is fulfilling #137 and the bribery-prohibition of Deuteronomy 16:19, but a court that warns people before the wrong is fully done — that tries to prevent the case rather than only resolve it — is doing what Deuteronomy 16:20 calls pursuit. The doubled word, tzedek tzedek, asks for justice that goes looking, not justice that merely sits and waits to be asked.

Key Figures

*
Jethro — The Counsel Behind the Courts
Watching Moses judge the whole nation alone, Jethro said plainly, "The thing that thou doest is not good" (Exodus 18:17), and proposed the tiered structure of judges that #137's 'judges in all thy gates' would later codify into law.
+
Moses — From Sitting Alone to a System That Pursues
Moses implemented Jethro's structure so completely that Exodus 18:26 could say the people "judged the people at all seasons" — justice no longer waiting for one man's availability, but actively reachable, the condition Deuteronomy 16:20's pursuit requires.

Study Questions

For reflection and group study
Deuteronomy 16:20 doubles its key word in Hebrew: 'tzedek, tzedek tirdof' — justice, justice, pursue. What might be lost if the verse simply said 'do justice' instead of 'pursue' it?
Jethro told Moses, 'The thing that thou doest is not good' (Exodus 18:17), even though Moses was working hard and judging honestly. Why might good intentions and hard work not be enough on their own?
Exodus 18:26 says the new judges 'judged the people at all seasons' — justice became continuously available rather than dependent on one person. How does availability itself relate to whether justice is being 'pursued'?
Jehoshaphat told his judges to 'warn them that they trespass not against the LORD' (2 Chronicles 19:10), rather than only ruling once a case was brought. What is the difference between a court that resolves disputes and one that also tries to prevent them?
This commandment sits between #137 (appoint judges) and #139 (judge righteously) — institution, then pursuit, then standard. Why might 'pursue justice' need to be its own commandment, separate from both establishing courts and ruling fairly within them?

Deuteronomy 16:20's doubled command — justice, justice, pursue — asks for courts that go looking for justice, not only courts that wait to be asked, as Jethro's reform and Jehoshaphat's instructions both show in practice.
