• Shemirat HaLashón (1876): theoretical Framework-spiritual and motivational, to “care for the language”; it combines sources, biblical and rabbinical with a practical guide.

4) Methodology and traits doctrinal

4.1. In halachah (Mishnah Berurah)

• Architecture of sources: works with the Shulchan Aruch Rabbi Yosef Caro and the gloss of the Rema, systematizes the ajaronim and defines a common practice. This makes it usable for the jewish “foot” and rabbis of the community.
• Criteria of psak: balance between rigor and hora'at sha unto (guideline for circumstances), especially in challenging environments; the clarity pedagogical and pastoral sensitivity.

4.2. In musar and social construction

• Power of the word: Jafets Chaim and Shemirat HaLashón found a “culture of speech”, which prohibits the reputational harm, even when the fact is certain, except for the following exceptions strict regulations (e.g., warn of danger, to prevent damage). The goal: protecting dignity, a sense of cohesion and community trust.
• Ethical economy: Ahavat Jésed and Sefat Tamim articulate a economy of the integrity: prohibition of deception, of the obligation of help with no-interest loans and culture of philanthropy responsible.
• Religion under pressure: Mahane Israel and Nidjei Israel adapt the practice to the reality of barracks, factories, and ports; preserve Shabbat, kashrut and tefillah in hostile contexts or new.

“The silence, when no damage, has more merit than a thousand speeches.”

5) Lessons nuclear (with applications)

Exceptions: prevention of damage, witness required by halacha or authority, protection of third parties, with strict conditions (proper intention, proportionality, without exaggeration). Practical result: protocols of speech in homes, schools, and media.

(b) Tzedakah and jésed structural

• Create gemajim community, to educate, to provide a stable, prioritizing basic needs and sustain institutions of Torah. Promotes a model of solidarity organized beyond the charity spontaneous.

c) Observance daily a clear and workable

• With Mishnah Berurah, sets standards practicable for prayer, synagogue and Shabbat; promotes pre-planning (e.g., eruv, preparations for Shabbat, schedules and minian). His tone is the normative pedagogical: to facilitate fulfillment, not just describe it.

d) work Ethic and business

• Transparency, measures, and honest weights, zero tolerance of deception in advertising or “vividness” commercial. Marketing without truth, it is an offence to morality.

(e) Resilience in diaspora and army

• To maintain identity in the factories and barracks (food, tefillah abbreviated with minian improvised, concessions limited). For migrants: seeking communities, rabbis, mikvaot and calendars to be reliable; negotiate with employers the sabbath rest when possible.

“Speak well of others is a form of justice; speak ill of him, a form of theft.”

6) Organization and leadership: Agudath Israel
