What is the meaning of "Erchamcha"?
1.
Rashi: I will love 1 You. The Targum of "v'Ahavta l'Re'echa" (Vayikra 19:18) is u'Srachem.
2.
Radak citing Ibn Ezra: I will request mercy from you.
3.
Malbim: I fill you with mercy. (Hashem is not 'moved'; mercy, which is a person who is moved and affected by seeing someone in difficulty, does not apply to Him.) I am the subject for which You are full of mercy, but not that it is because You are moved.

Radak: Love is the most one can do to draw close to the Creator. Avraham is called "Ohavi" (Yeshayah 41:8). Fear comes first. After one accustoms himself to fear, he comes to serve from love, even if he would not be rewarded for this.
