Okay, it was chapter 22. Verses 18 and 26
22:18. Son of man, the people of Israel are the worthless slag that remains after silver is smelted. They are the dross that is left over—a useless mixture of copper, tin, iron, and lead.
22:26 Your priests have violated my instructions and defiled my holy things. They make no distinction between what is holy and what is not. And they do not teach my people the difference between what is ceremonially clean and unclean.
The first verse tells what a useless mixture Gods people have become. The next verse blames the priests - teachers and leaders. They make no distinction between what is holy and what is not holy. And between what is clean and what is filthy.
And what I see is that, for the most part, we could overlay ourselves and not even be able to tell the difference between what Israel was in these verses and what we are currently. A useless mixture of the teachings of men and with teachers who don't make any distinction between what is holy and what isn't.
As for the other verses I was wondering about, I found them in Haggai 2, but they still don't make much sense to me. Although I did see that to touch a dead body defiled the sacrifice a priest was carrying in his robes and it seemed to fit together with: come out of her my people, do not share in her sins. But I might be the only one who sees a connection, I don't know.
