Teach Torah to Children

וְלִמַּדְתֶּם אֹתָם אֶת בְּנֵיכֶם
Source: Deuteronomy 11:19  ·  Maimonides, Sefer HaMitzvot, Positive #12

The Torah does not assume that children will absorb faith by osmosis. It commands transmission — explicit, deliberate, repeated teaching of Torah to the next generation. The commandment appears in multiple forms across Deuteronomy: when you sit in your house, when you walk by the way, when you lie down, when you rise up. Torah teaching is not a formal event scheduled once a week. It is embedded in the texture of daily life, in the answering of questions at the dinner table, in the explanation of why the family does what it does. When this commandment is kept, the chain holds. When it is broken, one generation is all it takes.

וְלִמַּדְתֶּם אֹתָם אֶת בְּנֵיכֶם לְדַבֵּר בָּם
"And ye shall teach them your children, speaking of them."

The Most Devastating Verse in Judges שׁוֹפְטִים

The book of Judges opens with the death of Joshua and the generation that had witnessed the conquest of Canaan. Their children inherited the land — and forgot the God who gave it. The transition from Joshua's generation to what followed took one generation:

וְגַם כָּל הַדּוֹר הַהוּא נֶאֶסְפוּ אֶל אֲבוֹתָיו וַיָּקָם דּוֹר אַחֵר אַחֲרֵיהֶם אֲשֶׁר לֹא יָדְעוּ אֶת יְהוָה
"And also all that generation were gathered unto their fathers: and there arose another generation after them, which knew not the LORD."
Judges 2:10

This single verse explains the entire book of Judges — the cycles of apostasy, oppression, deliverance, and relapse that dominate the next four centuries. The generation that witnessed the miracles of the Exodus and the conquest died. Their children had been raised in the land of Canaan, surrounded by Canaanite religion, and no one had fulfilled the commandment. They did not know the LORD. Not because they had rejected Him, but because no one had told them who He was.

Judges 2:10 is not a theological statement about human nature. It is an accountability statement about a generation of parents who failed to keep Deuteronomy 11:19.

The Passover Table: When Children Ask לַיְלֵי פֶּסַח

The Exodus commandments anticipate children's questions — and they anticipate them at the family table, not in a classroom:

וְהִגַּדְתָּ לְבִנְךָ בַּיּוֹם הַהוּא לֵאמֹר בַּעֲבוּר זֶה עָשָׂה יְהוָה לִי בְּצֵאתִי מִמִּצְרָיִם
"And thou shalt shew thy son in that day, saying, This is done because of that which the LORD did unto me when I came forth out of Egypt."

"This is done because of that which the LORD did unto me." Not "did to our ancestors." The parent speaks as if personally present at the Exodus — because the Torah requires every generation to inhabit the story, not merely to inherit it. The Passover Seder is the annual embodiment of this commandment: the entire ritual is designed to generate children's questions and give adults the framework to answer them. The four children described in the Haggadah — wise, wicked, simple, and the one who cannot yet ask — represent the range of how children receive this transmission. The commandment does not assume every child receives Torah the same way. It requires the parent to meet each child where they are.

Moses' Warning: Forget to Teach, and You Lose Everything אַזְהָרָה

רַק הִשָּׁמֶר לְךָ וּשְׁמֹר נַפְשְׁךָ מְאֹד פֶּן תִּשְׁכַּח אֶת הַדְּבָרִים אֲשֶׁר רָאוּ עֵינֶיךָ וּפֶן יָסוּרוּ מִלְּבָבְךָ כֹּל יְמֵי חַיֶּיךָ וְהוֹדַעְתָּם לְבָנֶיךָ וְלִבְנֵי בָנֶיךָ
"Only take heed to thyself, and keep thy soul diligently, lest thou forget the things which thine eyes have seen, and lest they depart from thy heart all the days of thy life: but teach them thy sons, and thy sons' sons."

Moses identifies a specific mechanism of failure: you can forget what you have personally witnessed. Not only can you forget — you are in danger of forgetting. The response to this danger is not better memory techniques. It is transmission. The act of teaching your children is the act of preserving your own memory. Moses links the two in a single breath: keep your soul diligently so you do not forget, and teach your children. The teacher is always also the one being formed by the act of teaching.

Psalm 78: The Explicit Purpose of the Chain תְּהִלִּים עח

Psalm 78 opens with a declaration of intent: we will tell the next generation the praises of God and His deeds. It then names the explicit purpose of this generational transmission:

לְמַעַן יֵדְעוּ דּוֹר אַחֲרוֹן בָּנִים יִוָּלֵדוּ יָקֻמוּ וִיסַפְּרוּ לִבְנֵיהֶם
"That the generation to come might know them, even the children which should be born; who should arise and declare them to their children."
Psalm 78:6

The chain is described in motion: this generation tells the next, who tells the next, who tells the next. The chain is not incidental — it is the mechanism by which Israel maintains its identity and relationship with God across centuries. Psalm 78 then names what the chain produces:

וְיָשִׂימוּ בֵאלֹהִים כִּסְלָם וְלֹא יִשְׁכְּחוּ מַעַלְלֵי אֵל וּמִצְוֹתָיו יִנְצֹרוּ
"That they might set their hope in God, and not forget the works of God, but keep his commandments."
Psalm 78:7

Three outcomes: hope in God, memory of God's works, obedience to God's commandments. These are not three separate results. They are the same result described three ways. A generation that keeps this commandment will produce children who trust God, remember what He has done, and live according to His Torah. A generation that breaks this commandment produces the next Judges 2:10.

Jehoshaphat: National Transmission Infrastructure יְהוֹשָׁפָט

וַיְלַמְּדוּ בִּיהוּדָה וְעִמָּהֶם סֵפֶר תּוֹרַת יְהוָה
"And they taught in Judah, and had the book of the law of the LORD with them."
2 Chronicles 17:9

Jehoshaphat's initiative — sending princes, Levites, and priests with the Torah scroll to teach in every city of Judah — was the most ambitious implementation of this commandment by any king in the divided monarchy. He treated the commandment to teach Torah as a national responsibility, not merely a private family one. Every city in Judah was reached. The result (2 Chr 17:10) was that surrounding nations feared Judah — not because of military strength but because of the visible formation of a Torah-knowing people.

Key Figures

💔
The Judges Generation — The Warning
Judges 2:10 is the Bible's most direct statement of what this commandment's failure costs: not heresy, not rebellion, but ignorance. "They knew not the LORD." One generation of transmission failure produced four centuries of cycles.
🍷
The Passover Parent — The Practice
Every Israelite parent at the Passover table embodies this commandment. The Seder's structure — anticipating children's questions and providing answers — is Torah pedagogy built into ritual. The table is the classroom.
📖
Jehoshaphat — The Infrastructure
His deployment of Torah teachers across all Judah shows that the commandment scales. Personal family transmission matters. But a nation that also creates institutional structures for Torah education multiplies the effect.

Study Questions

For reflection and group study
Judges 2:10 says the post-Joshua generation "knew not the LORD" — in one generation. What conditions allowed this to happen? Was it sudden or gradual? And what does "know" mean in this context — intellectual knowledge or relational experience?
See Judg 2:10–11; Hos 4:6; Jer 9:3
The Passover command (Ex 13:8) says to tell your son "the LORD did this unto ME" — first person, not third person. Why does Moses use first-person language here? What does it mean to own a story that happened before you were born?
See Ex 13:8; Deut 5:3; Ps 78:5–7
Moses says in Deut 4:9 that the act of teaching your children prevents you from forgetting. How does teaching function as a preservation mechanism for the teacher's own faith? What does this say about the relationship between intergenerational transmission and personal conviction?
See Deut 4:9; Prov 22:6; Isa 38:19
Psalm 78:7 says successful transmission produces three things: hope in God, memory of His works, and obedience to His commandments. Why does hope come first? What is the relationship between knowing God's past acts and trusting Him in the present?
See Ps 78:7; Rom 15:4; 1 Cor 10:11
Jehoshaphat sent teachers to every city — making Torah education a national program. What is the difference between this institutional approach and the household-level commandment of Deuteronomy 11:19? Are they complementary or in tension?
See 2 Chr 17:7–9; Deut 11:19; Neh 8:1–8
