Parashat Bo 5786: Slavery With Interest
Why connect the slaying of the firstborn and lending with interest?

(ד) וַיֹּ֣אמֶר מֹשֶׁ֔ה כֹּ֖ה אָמַ֣ר יְהֹוָ֑ה כַּחֲצֹ֣ת הַלַּ֔יְלָה אֲנִ֥י יוֹצֵ֖א בְּת֥וֹךְ מִצְרָֽיִם׃ (ה) וּמֵ֣ת כׇּל־בְּכוֹר֮ בְּאֶ֣רֶץ מִצְרַ֒יִם֒ מִבְּכ֤וֹר פַּרְעֹה֙ הַיֹּשֵׁ֣ב עַל־כִּסְא֔וֹ עַ֚ד בְּכ֣וֹר הַשִּׁפְחָ֔ה אֲשֶׁ֖ר אַחַ֣ר הָרֵחָ֑יִם וְכֹ֖ל בְּכ֥וֹר בְּהֵמָֽה׃

(4) Moses said, “Thus says GOD: Toward midnight I will go forth among the Egyptians, (5) and every [male] first-born in the land of Egypt shall die, from the first-born of Pharaoh who sits on his throne to the first-born of the slave woman who is behind the millstones; and all the first-born of the cattle.

David Graeber, Debt: The First 5,000 Years, 28: "[Money has the] capacity to turn morality into a matter of impersonal arithmetic—and by doing so, to justify things that would otherwise seem outrageous or obscene."
1. Lending With Interest

אָמַר הַקָּדוֹשׁ בָּרוּךְ הוּא: אֲנִי הוּא שֶׁהִבְחַנְתִּי בְּמִצְרַיִם בֵּין טִפָּה שֶׁל בְּכוֹר לְטִפָּה שֶׁאֵינָהּ שֶׁל בְּכוֹר, אֲנִי הוּא שֶׁעָתִיד לִיפָּרַע מִמִּי שֶׁתּוֹלֶה מְעוֹתָיו בְּגוֹי וּמַלְוָה אוֹתָם לְיִשְׂרָאֵל בְּרִבִּית, וּמִמִּי שֶׁטּוֹמֵן מִשְׁקְלוֹתָיו בְּמֶלַח, וּמִמִּי שֶׁתּוֹלֶה קָלָא אִילָן בְּבִגְדוֹ וְאוֹמֵר: ״תְּכֵלֶת הוּא״.

Rava explains: The Holy One, Blessed be He, said: I am He Who distinguished in Egypt between the drop of seed that became a firstborn and the drop of seed that did not become a firstborn, and I killed only the firstborn. I am also He Who is destined to exact punishment from one who attributes ownership of his money to a gentile and thereby lends it to a Jew with interest. Even if he is successful in deceiving the court, God knows the truth. And I am also He Who is destined to exact punishment from one who buries his weights in salt, as this changes their weight in a manner not visible to the eye. And I am also He Who is destined to exact punishment from one who hangs ritual fringes dyed with indigo [kala ilan] dye on his garment and says it is dyed with the sky-blue dye required in ritual fringes. The allusion to God’s ability to distinguish between two apparently like entities is why the exodus is mentioned in all of these contexts.

(כד) אִם־כֶּ֣סֶף ׀ תַּלְוֶ֣ה אֶת־עַמִּ֗י אֶת־הֶֽעָנִי֙ עִמָּ֔ךְ לֹא־תִהְיֶ֥ה ל֖וֹ כְּנֹשֶׁ֑ה לֹֽא־תְשִׂימ֥וּן עָלָ֖יו נֶֽשֶׁךְ׃

(24) If you lend money to My people, to the poor among you, do not act toward them as a creditor; exact no interest from them.

(לה) וְכִֽי־יָמ֣וּךְ אָחִ֔יךָ וּמָ֥טָה יָד֖וֹ עִמָּ֑ךְ וְהֶֽחֱזַ֣קְתָּ בּ֔וֹ גֵּ֧ר וְתוֹשָׁ֛ב וָחַ֖י עִמָּֽךְ׃ (לו) אַל־תִּקַּ֤ח מֵֽאִתּוֹ֙ נֶ֣שֶׁךְ וְתַרְבִּ֔ית וְיָרֵ֖אתָ מֵֽאֱלֹהֶ֑יךָ וְחֵ֥י אָחִ֖יךָ עִמָּֽךְ׃ (לז) אֶ֨ת־כַּסְפְּךָ֔ לֹֽא־תִתֵּ֥ן ל֖וֹ בְּנֶ֑שֶׁךְ וּבְמַרְבִּ֖ית לֹא־תִתֵּ֥ן אׇכְלֶֽךָ׃ (לח) אֲנִ֗י יְהֹוָה֙ אֱלֹ֣הֵיכֶ֔ם אֲשֶׁר־הוֹצֵ֥אתִי אֶתְכֶ֖ם מֵאֶ֣רֶץ מִצְרָ֑יִם לָתֵ֤ת לָכֶם֙ אֶת־אֶ֣רֶץ כְּנַ֔עַן לִהְי֥וֹת לָכֶ֖ם לֵאלֹהִֽים׃ {ס}

(35) If your kin, being in straits, come under your authority, and are held by you as though resident aliens, let them live by your side: (36) do not exact advance or accrued interest, but fear your God. Let your kin live by your side as such. (37) Do not lend your money at advance interest, nor give your food at accrued interest. (38) I am the ETERNAL your God, who brought you out of the land of Egypt, to give you the land of Canaan, to be your God.

(יג) בַּנֶּ֧שֶׁךְ נָתַ֛ן וְתַרְבִּ֥ית לָקַ֖ח וָחָ֑י לֹ֣א יִֽחְיֶ֗ה אֵ֣ת כׇּל־הַתּוֹעֵב֤וֹת הָאֵ֙לֶּה֙ עָשָׂ֔ה מ֣וֹת יוּמָ֔ת דָּמָ֖יו בּ֥וֹ יִֽהְיֶֽה׃

(13) has lent at advance interest, or exacted accrued interest—shall he live? He shall not live! If he has committed any of these abominations, he shall die; he has forfeited his life.

(1) There was a great outcry by the common folk against their fellow Jews. (2) Some said, “Our sons and daughters are numerous; we must get grain to eat in order that we may live!” (3) Others said, “We must pawn our fields, our vineyards, and our homes to get grain to stave off hunger.” (4) Yet others said, “We have borrowed money against our fields and vineyards to pay the king’s tax. (5) Now we are as good as our kin, and our children as good as theirs; yet here we are subjecting our sons and daughters to slavery—some of our daughters are already subjected—and we are powerless, while our fields and vineyards belong to others.” (6) It angered me very much to hear their outcry and these complaints. (7) After pondering the matter carefully, I censured the nobles and the prefects, saying, “Are you pressing claims on loans made to your own kin?” Then I raised a large crowd against them

David Graeber, Debt: The First 5,000 Years, 115-116: "[When] Nehemiah returned home [from Babylonia], he found himself confronted with a social crisis. All around him, impoverished peasants were unable to pay their taxes; creditors were carrying off the children of the poor. His first response was to issue a classic Babylonian-style “clean slate” edict—having himself been born in Babylon, he was clearly familiar with the general principle. All non-commercial debts were to be forgiven. Maximum interest rates were set. At the same time, though, Nehemiah managed to locate, revise, and reissue much older Jewish laws, now preserved in Exodus, Deuteronomy, and Leviticus, which in certain ways went even further, by institutionalizing the principle. The most famous of these is the Law of Jubilee: a law that stipulated that all debts would be automatically canceled “in the Sabbath year” (that is, after seven years had passed), and that all who languished in bondage owing to such debts would be released."
"In the Bible, as in Mesopotamia, “freedom” came to refer above all to release from the effects of debt. Over time, the history of the Jewish people itself came to be interpreted in this light: the liberation from bondage in Egypt was God’s first, paradigmatic act of redemption…"
