That is something I would like to hear/read a d'rash about. Since I am a full time college student right now, I don't have time to really study too much Hebrew beyond the class I teach on Wednesday nights, the weekly parashot and my religion class....I guess that's quite a bit. But if you knew me, you would know that I could study Hebrew 8 hours a day!
Here is the verse: You can see our shoresh in the first and last word of the verse:
יְראוּ אֶת-יְהוָה קְדֹשָׁיו: כִּי-אֵין מַחְסוֹר, לִירֵאָיו
