EXTRA · Side-ring · Parashas Shoftim · Passuk 19:09
When you keep all this commandment to do it, which I command you today, to love the Eternal your God and to walk in His ways all the days, then you shall add for yourself another three cities to these three.
Chazal / classical source (beyond TT-numbered main-ring units): Sifrei Devarim 185.
Lemma: לְאַהֲבָה אֶת ה׳ אֱלֹהֶיךָ וְלָלֶכֶת בִּדְרָכָיו.
English: ‘To love the Eternal your God and to walk in His ways all the days’ – this is love and attachment.
Derash on the inner requirement (Sifrei) — love of Hashem and walking in His ways are the prerequisite.
The addition of the three cities is framed by the demand to love Hashem and to walk in His ways continuously.
