קבלה על בראשית 17:1

The second precept is that the precept of fear is strongly attached to and never disconnected from the precept of love. A person should love his Master wholly. And what is perfect love? It is great love, as it is written, "walk before Me and be perfect" (Gen. 17:1). Meaning, to be whole with love. Thus it is written, "And Elohim said, Let there be light" (Gen. 1:3). This perfect love is called great love. And here it appears as a precept, that a person should love his Master properly.
