1.Consisting of diverse and unrelated parts or persons
2.Lacking standards of selection, especially engaging in sexual intercourse indiscriminately with more than one partner
This only found in
(Gal 5:19-26 ISV) Now the actions of the flesh are obvious: sexual immorality, impurity, promiscuity, 5:20 idolatry, witchcraft, hatred, rivalry, jealously, outbursts of anger, quarrels, conflicts, factions, 5:21 envy, murder, drunkenness, wild partying, and things like that. I am telling you now, as I have told you in the past, that people who practice such things will not inherit the kingdom of Almighty. 5:22 But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, 5:23 gentleness, and self-control. There is no law against such things. 5:24 Now those who belong to the Messiah Yahshua have crucified their flesh with its passions and desires. 5:25 Since we live by the Spirit, by the Spirit let us also be guided. 5:26 Let's stop being arrogant, provoking one another and envying one another.
[So what does this say to us? We need boundaries! In today's world sexual immorality as spelled out in scripture is laughed at. Yet we see all around us the out comes of such actions. Children without two parents, aborted children even in marriages, abandoned children and mates.
I was a single parent most of the time and let me tell you there is no substitute for a helper you can count on when raising children.
Children are meant to be a gift, not a burden.
I was prepared/trained to be a worker, not a parent, and when the children came I had no idea how to train them up in the way they should go. So it should be no surprise they also made a mess of their lives and their children's lives as well.
So what is the answer? Read and apply the instructions given in the first five books of scripture. Teach them and live them as an example of the good life. These teaching are ours so we will know the house rules when we go home, and no one who refuses to obey will have one of heavens mansions. The choice is ours: obedience leads to a righteous life, a righteous life lived in love leads home. Don't leave out those fruits of the spirit we read about above.
PS: Promiscuity is also seen in our willingness to allow the forms of worship used for idols to enter into our worship of Yahweh.
