Parshat Ki Teitzei contains a seemingly puzzling instruction regarding the evil nation of Amalek. The Torah tells Israel to eradicate Amalek - but only after the Jewish people have settled in Eretz Yisrael and G-d has granted them menuchah, rest, from their surrounding enemies.
Why wait until then? One might have expected the opposite: deal with Amalek while the danger is still immediate.
To understand the significance of this timing, we first need to look at what the Torah says about Amalek:
“Remember what Amalek did to you on the way, when you left Egypt; how he happened upon you on the way and struck those of you who were weak at the rear, when you were faint and weary, and he did not fear G-d" (Deuteronomy 25:17-18).
Amalek was the first nation to attack the Jewish people after the Exodus. It struck a people who had only recently emerged from slavery and deliberately targeted those who were weakest and most vulnerable. The mitzvah to remember what Amalek did applies throughout the generations.
The Sefer HaChinuch (attributed to Rabbi Aharon HaLevi of Barcelona, 1235-1303) says this mitzvah teaches a broader lesson: anyone who brings suffering upon Israel is hated before Hashem, and his downfall will correspond to the evil he seeks to inflict upon us.
Amalek therefore became more than one enemy encountered in the desert. It became the paradigm of an enemy whose hostility toward Israel must neither be forgotten nor dismissed.
The Torah then turns from remembrance to action:
“And it shall be, when the Lord your G-d gives you rest from all your enemies around you, in the land that the Lord your G-d gives you as an inheritance to possess, you shall erase the memory of Amalek from beneath the heavens; you shall not forget" (Deuteronomy 25:19).
The Torah is dealing here with two different ideas: preserving the memory of what Amalek did, and taking national action against Amalek under the circumstances set out in the verse.
The Talmud (Sanhedrin 20b) further teaches that upon entering the Land, the Jewish people were given three obligations: appoint a king, destroy Amalek, and build the Beit Hamikdash, the Holy Temple.
But that still leaves our original question unanswered. Why does the Torah specify that Amalek is to be eradicated only after G-d has granted Israel menuchah?
Perhaps because an enemy is easiest to recognize when he is attacking. In the middle of a battle, no one needs to be reminded that the threat is real or that the enemy wishes him harm.
The more difficult test comes afterward.
Once the fighting has ended and normal life begins to return, people naturally want to put the conflict behind them. As time passes, yesterday’s threats can start to seem distant, and an enemy who is temporarily quiet can appear less dangerous than he really is.
That may help explain the unusual emphasis on menuchah. The Torah places the eradication of Amalek at a moment when Israel is no longer fighting for its immediate survival - precisely when the temptation to forget the nature of the enemy can become stronger.
The words that frame the passage now come into sharper focus. It begins with Zachor - “Remember" - and concludes with Lo tishkach - “Do not forget." Zachor tells us to remember what Amalek did; Lo tishkach warns us not to allow the passage of time and the return of normalcy to dull that memory.
The Torah is not telling us to live in constant fear. Menuchah is itself a blessing. But peace can create a temptation of its own: to mistake quiet for a permanent change in the intentions of those who wish us harm.
So when the Jewish people finally do achieve a measure of peace, they must resist the most subtle danger of all: allowing security to become complacency.
