#460 Negative commandment Exodus 22:20

The cited verse

The Hebrew (Masoretic Text)

וְגֵר לֹא תוֹנֶה וְלֹא תִלְחָצֶנּוּ

In Maimonides’ words

How Maimonides defines this commandment in his Sefer HaMitzvot — his own words, shown as a primary source.

הזהירנו מהונות גר צדק ומהזיקו במקח וממכר. והוא אמרו ולא תלחצנו. ולשון מכילתא לא תלחצנו בממון. וכבר התבאר בגמרא מציעא (נ"ט:) שהמאנה את הגר עובר משום לא תונו איש את אחיו ומשום גר לא תונו והלוחצו עובר משום לא תלחצנו מוסף על האזהרה שהוא נכלל עם ישראל רוצה לומר אונאת ממון. (שם, שם):

He prohibited us from wronging the convert and causing him damage in buying and selling. And that is His saying, "and you shall not oppress him" (Exodus 22:20). And the language of the Mekhilta (Mekhilta d'Rabbi Yishmael 22:20:1) is,"'You shall not oppress him,' is with money." And it has already been explained in the Gemara, Metzia (Bava Metzia 59b), that one who wrongs the convert transgresses on account of, "you shall not wrong your brother" (Leviticus 25:14), and on account of, "You shall not wrong a convert"; and one who oppresses him, transgresses on account of, "and you shall not oppress him," in addition to the prohibition in which he is included with all of Israel - meaning to say, financial wrong. (See Parashat Behar; Mishneh Torah, Sales 14.)

Beside the older legal codes of its world

The commandment set beside the ancient Near-Eastern legal collections scholars compare it to — a descriptive comparison, not a claim of dependence.

Where this commandment meets modern human-rights frameworks

One modern normative lens, attributed to it — not GEBible’s assessment. Each row names the framework it measures against and the catalog’s own classification of the relation.

This framework catalogues tensions; it records agreement in only one of its entries. The near-total tension rate is the shape of the instrument, not a finding.

No tension with the catalogued modern frameworks is recorded here.
