what was Douglass's comment about the holiness of marraiage for both whites and blacks, in what page in the Narrative?

I found two quotes that fit in with the destruction of marriage, but neither (in context) is cited as relating to both whites and blacks. Douglass seems to be dicussing the destruction of marriage in general terms, but also terms that would pertain to marriages within the bonds of slavery.

"As if, when the marriage institution is abolished, concubinage, adultery, and incest, must not necessarily abound; when all the rights of humanity are annihilated, any barrier remains to protect the victim from the fury of the spoiler; when absolute power is assumed over life and liberty, it will not be wielded with destructive sway!" (Page 9)

This next quote refers to preachers who "preach" the sanctity of marriage but embrace slavery.

"He who is the religious advocate of marriage robs whole millions of its sacred influence, and leaves them to the ravages of wholesale pollution. The warm defender of the sacredness of the family relation is the same that scatters whole families,—sundering husbands and wives, parents and children, sisters and brothers,—leaving the hut vacant, and the hearth desolate." (Page 94)
