Musar sur Les Psaumes 48:15

כִּ֤י זֶ֨ה ׀ אֱלֹהִ֣ים אֱ֭לֹהֵינוּ עוֹלָ֣ם וָעֶ֑ד ה֖וּא יְנַהֲגֵ֣נוּ עַל־מֽוּת׃

que ce Dieu est notre Dieu pour l’éternité! C’est lui qui nous dirigera jusqu’à l’heure de la mort.

Mesilat Yesharim

And in the Midrash (Vayikra Rabba 11:9) on the verse (Tehilim 48:15) "He shall lead us in youth" - [filled] with zeal as young maidens, as it is said: "in the midst of maidens playing the timbrels" (Tehilim 68:26) ["in youth" and "young maidens" are related words in Hebrew].

Mesilat Yesharim

The means through which Zeal is acquired are the same ones through which Watchfulness is acquired, and their levels are likewise similar as I wrote earlier.
