'Promiscuous' in the Bible

Then your survivors will remember Me among the nations where they are taken captive, how I was crushed by their promiscuous hearts that turned away from Me and by their eyes that lusted after their idols. They will loathe themselves because of the evil things they did, their detestable practices of every kind.

You engaged in promiscuous acts with Egyptian men, your well-endowed neighbors, and increased your prostitution to provoke Me to anger.

“Now her sister Oholibah saw this, but she was even more depraved in her lust than Oholah, and made her promiscuous acts worse than those of her sister.
