Prov 2:18

“For her house is inclined to death, etc. Every behavior of the adulteress leads to destruction, and although she seems sweet and gentle, she will feel no less vengeance at the end than those who serve with open impiety by robbery. The house of the adulteress, her very flesh, in which she is laid under degradation and lust, can be understood, which at the last time of judgment, will rise not to life, but to eternal death. But also the house of heretics, because it is built upon sand, even when it seems to stand, leans towards ruin, and by its own growth as by certain paths, it tends to the company of the impious, that is, it extends to the torments of evil spirits.”

“for her house sinks to death This refers back to “to save you, etc.” for whoever comes to her house will sink and slip as if down an incline that leads to death, and the Torah will guard you from this fall. Hence, it is a great thing for you. the dead Heb. רפאים, those who neglect (נרפים) the way of goodness and are forsaken without support until they fall into Gehinnom.”
