"In him who loves there is neither blindness nor occasion of stumbling [to himself]: in him who does not love, there is both blindness and occasion of stumbling. He who hates his brother, is both a stumbling-block to himself, and stumbles against himself and everything within and without; he who loves has an unimpeded path" [BENGEL].
