Which go a whoring after their idols (Isaiah 57)

Isaiah chapter 57 has a lot of notes on it, one of which I know I addressed before, but I'm having a hard time finding. No matter, I can address the question of Has there ever been a righteous person? by referring to my post on 2Samuel 22 where I explained that the word "righteous" is used a bit loosely in the Bible overall and can mean different things. However, the question of Will the righteous flourish? is really not a contradiction, as even those who do flourish will eventually die; that's just life. I think the verse here is just saying there's something sad about the perishing of the righteous in particular.

Verse three addresses the "sons of the sorceress, the seed of the adulterer and the whore." Yeah, it's harsh, although I'm not really clear on why this is a verse to be marked with the "women" icon; I suppose sorceresses and whores are women (checking the Hebrew, "adulterer" is also feminine, so I don't know why it isn't "adulteress"), but the issue with them is not their femininity. I mean, since we're apparently addressing the "sons" of these women, it's not like you get to choose your parentage, but perhaps these are metaphorical "sons" who are engaged in similar behaviors? It does go on to talk about idolatry in verses five through eight, where the sexual imagery may be metaphorical or literal, as some idols were of sex goddesses, but sexuality and spirituality are often closely linked in scripture. Verse nine is probably closely related to these verses, with the idea of seducing the king into idolatry as well. I addressed the subject of Is it OK to use perfume? in John chapter 12, where I suggested it's a stretch to call it a contradiction.

The rest of the chapter is perhaps a bit opaque, as it's not fully clear who it's being addressed to, but I'm guessing Israel, with respect to the idol worship. God calls them to remember how he is faithful, and how idols are not. Verse 15 is interesting because it talks about how God lives "in the high and holy place" with those who are humble; could this be an Old Testament reference to Heaven as an afterlife? I don't know; it could be talking about the Temple, possibly. The chapter ends with a warning that there is no peace for the wicked.
