Regarding 4Q174, I found an interesting article on it by Philip Church, in which he discusses certain resemblances between it and Hebrews:
Ever since 4Q174 was first published, scholars have noted connections with the Epistle to the Hebrews, usually related to the appearance of 2 Sam 7:14 (4Q174 1 III 11) and Ps 2 (4Q174 1 III 18). Hebrews 1:5 juxtaposes 2 Sam 7:14 and Ps 2:7, and Ps 2:7 also appears in Heb 5:5. As Brooke maintains, "both authors were acquainted with a tradition whereby 2 Samuel 7 and Psalm 2 belong together," although I would add that the authors do different things with these texts. But there is more than this to 4Q174 and Hebrews. In what follows I will discuss 4Q174 II 19 – 1 III 13 and will then turn my attention to Hebrews and draw out some similarities between the two texts. This essay is an exercise in the mutual illumination of these two texts.

This is what I mean about the DSS and Christianity. It doesn't matter to me if all the DSS were from the first century BCE (or earlier) and not the first century CE. These kinds of resemblances make me think that if 4Q174 (and the related Damascus Document) isn't from the first century CE then there must have been a sect or a way of thinking that was like Christianity (at least in certain respects) before there was Christianity (as Wise and Knohl propose).
The article also uses the Wise, Abegg, Cook translation of 4Q174 -but not the line about the sons of Zadok!
And here is the translation (page 355) and the Hebrew (line 17 on page 354) from Martinez and Tigchelaar:
I have to say that I'm not sure how to take this translation now. It follows this citation of Ezekiel 44:10:This (refers to) the sons of Zadok and (to) the m[e]n of [the]ir council, those who see[k jus]tice eagerly, who have come after them to the council of the community.

"And (this refers to) those about whom it is written in the book of Ezekiel, the prophet, that they [the Levites] should not defile themselves anymore with all their idols."
My rough translation of the Hebrew (using a dictionary, out of curiosity) is:
They are the sons of Zadok and the men of their council who pursue righteousness who come after them to the council of the community.
The only part that confuses me here is "who come after them" מאחריהמה
I can't figure that one out, and that looks like the part I don't really understand in Martinez above ("who have come after them to the council of the community."
Who is "them"? Are they the idolatrous Levites in the underlying Ezek. 44:10? And what does "come after" mean here?
