Vayikra – Peah and Leket
Leviticus 19:9-10
The Torah commands leaving the corners of the field (peah) and fallen gleanings (leket) for the poor and the stranger, establishing an agricultural form of obligatory giving.
וּֽבְקֻצְרְכֶם֙ אֶת־קְצִ֣יר אַרְצְכֶ֔ם לֹ֧א תְכַלֶּ֛ה פְּאַ֥ת שָׂדְךָ֖ לִקְצֹ֑ר וְלֶ֥קֶט קְצִֽירְךָ֖ לֹ֥א תְלַקֵּֽט׃ וְכַרְמְךָ֙ לֹ֣א תְעוֹלֵ֔ל וּפֶ֥רֶט כַּרְמְךָ֖ לֹ֣א תְלַקֵּ֑ט לֶֽעָנִ֤י וְלַגֵּר֙ תַּעֲזֹ֣ב אֹתָ֔ם אֲנִ֖י יְהֹוָ֥ה אֱלֹהֵיכֶֽם׃
When you reap the harvest of your land, you shall not reap all the way to the edges of your field, or gather the gleanings of your harvest. You shall not pick your vineyard bare, or gather the fallen fruit of your vineyard; you shall leave them for the poor and the stranger: I the ETERNAL am your God.
Why it matters — One of the earliest codified forms of mandatory charity, showing that tzedakah is not voluntary but legally imposed.
