Hilchos Shabbos Table Learning

A Weekly Guide to Shabbos Laws for Personal Study and Family Discussion

 

✨ This Week’s Topic ✨

🍞 Eruv Tavshilin
Preparing on Yom Tov for Shabbos

 

📜 The Law

❓ When is Eruv Tavshilin required?
✅ Whenever Yom Tov falls on Friday (Erev Shabbos)

📌 One must make an Eruv Tavshilin on Erev Yom Tov in order to:
• 🍳 Cook on Friday for Shabbos
• 🔥 Light Shabbos candles
• 🛠️ Prepare all Shabbos needs

 

⚠️ Critical Rule: Cooking Time
Even with an Eruv Tavshilin:

❗ Food must be ready before sunset on Yom Tov
❌ If there isn’t enough time for it to be edible before sunset → cooking is Biblically forbidden

📌 Many people are unaware of this important limitation

 

📅 When Is It Done?

🕓 Best Time:
• After daybreak on Erev Yom Tov

🟡 Allowed (if needed):
• Even from the night before

⏳ Last Chance:
• Until nightfall (Tzeis Hakochavim)

 

❗ If One Forgot:

🟡 Before nightfall:
✅ May still perform Eruv Tavshilin

🌗 After nightfall:

• Thursday–Friday Yom Tov:
  ✅ May (bedieved) make Eruv with a tnaiy (condition)
• Friday–Shabbos Yom Tov:
  ❌ A tnaiy does NOT help
  👉 Must consult a Rav

 

🥖 How Is It Done?

📦 The Foods Required:
• 🍞 Whole bread or matzah (size of a kibeitzah)
• 🍖 Cooked food (at least a kezayis)

✅ Preferably use an honorable food (meat or fish)

 

🤝 Including Others (Mizakeh):

✅ Custom: Acquire the Eruv on behalf of others in the city

🔄 How:
• Give the food to someone (non-dependent household member)
• Say:
👉 “I hereby acquire this for anyone who wishes to rely on this Eruv”
• The person lifts it one tefach
• Take it back and proceed with the bracha

⚠️ Who may be used:
• ✅ Non-family member
• ✅ Married child
• ✅ Independent child over Bar/Bas Mitzvah
• ⚠️ If no one else → wife or older child may be used

❌ Not valid:
• Dependent children under Bar/Bas Mitzvah

🙏 The Bracha

ברוך אתה ה’ אלוקינו מלך העולם אשר קדשנו במצותיו וצונו על מצות עירוב

📌 Then say (in a language you understand):

“With this Eruv it is permitted to bake, cook, insulate food, light candles, and prepare all needs from Yom Tov for Shabbos.”

🧾 Aramaic text:

בדין יהא שרא לנא לאפויי ולבשולי ולאטמוני ולאדלוקי שרגא ולתקנא ולמעבד כל צרכנא מיומא טבא לשבתא לנא ולכל ישראל הדרים בעיר הזאת

 

🍽️ After Making the Eruv

✅ Put the food away safely

📌 You must not eat it before finishing Shabbos preparations

 

🍞 Best Practice (Mitzvah Min Hamuvchar):
• Use the bread for Lechem Mishneh on Shabbos
• Some use it for:

• First meal 🍽️
• Second meal 🍽️
• Eat it at the third meal 🍽️

 

⚠️ If the Food Is Lost or Eaten Early:

🍖 Cooked food:
❌ Cannot continue cooking unless a kezayis remains

🍞 Bread only:
✅ Still permitted to prepare

 

❓ Common Questions

🥶 Can frozen food be used?
✅ Yes

🏷️ Food from a Hashgacha you don’t use?
⚖️ Preferably not, but valid if needed

👤 Can you use food you don’t own?
❌ No — it must belong to you

 

📢 Community Reminder

✅ It is important to remind the ציבור:
• 🏫 Shul notices
• 🌐 Community boards/websites
• 📣 Announcements after davening

 

🧭 Bottom Line

✅ Yom Tov on Friday → Must make Eruv Tavshilin
✅ Requires bread + cooked food
✅ Enables cooking/preparing for Shabbos
⚠️ Must finish cooking before sunset

 

🧠 Shabbos Takeaway

Eruv Tavshilin reminds us that even when preparing for Shabbos begins on Yom Tov,
📌 we do so with structure, awareness, and halachic boundaries.

✨ Preparation for Shabbos is not just practical — it’s part of honoring the Kedushah of both Yom Tov and Shabbos.
