The word for lovers, ahab, refers to people that are closest to you, such as in intimacy or as family, such as brothers or sisters and such.
Friends, rea, refers to associates or fellow workers or people with which you have a regular relationship of some type.
Kinsman, qarowb, refers to neighbors, or those whom you know, but are not close at hand.
In other words, the impact on ones entire life, runs the entire range of social interaction, whether it be intimate or distant.
The sore, nega, is a reference to the infirmity whatever it is. It can be a sickness, a disease, an illness, an injury of some kind, an attitude, or whatever. But no matter what the infirmity is, it is bad enough to drive away everyone that is in your social periphery, either near or far.
And of course the spiritual lesson here, is that, spiritual decline or the absence of the spiritual life, will have an impact on your relationships, no matter what they are.
Not to say that the spiritual life will give you better relationships by default, because this is the Devils world, and other people have flaws also.
If you yourself have a poor quality spiritual life, then your relationships will be of poor quality, sooner or later.
Advancing in your spiritual life, gives you more discernment, helping you make better choices, and providing for you a better quality of life overall.
