He then moved away from there and dug another well, and this time it was not disputed, so he named it Rechovos (“Expansiveness”), and he said: “Now G‑d has broadened us, and we shall be fruitful in the land.” (ibid. 26:22) Inner fear [of G‑d] is called “Rechovos,” for there is no fear of the kelipot there, so that one must limit oneself because of them – through suffering, small-mindedness and [self]-afflictions – to prevent them from leeching on to holiness. Rather, “Now G‑d has broadened us” – with the inner essence of fear that is called Rechovos. Then “we shall be fruitful in the land” – we will give forth fruits, to turn the multitude from sin, to be a Rabbi and a Rebbe, to uplift and create souls. However, if a person is a Rabbi or Rebbe yet lacks inner fear, he is from the kelipat nogah. Leket Imrei Peninim, p. 209b
