The first part of the quote is actually from General Golan. Here is a slightly different translation:
If there is one thing that is scary in remembering the Holocaust, it is noticing horrific processes which developed in Europe – particularly in Germany – 70, 80, and 90 years ago, and finding remnants of that here among us in the year 2016 International Business Times
In the same speech, he says this, which does not match the claim that is attributed to him about organ harvesting and human trafficking:
The IDF has taken pride, from time immemorial, in our ability to investigate serious incidents without prejudice, to courageously investigate problematic conduct, and to assign full responsibility for the good as well as for the bad. We didn’t justify, we didn’t cover up, we didn’t plaster over the cracks, we didn’t turn a blind eye and we made no excuses. Our way was, and will always be, the way of the truth and responsibility even when the truth is difficult
He later also clarified:
The IDF is a moral army that respects the rules of engagement and protects human dignity.
No reputable news source mentions organ harvesting. Even the self-described anti-zionist mondoweiss makes no mention of it.
Americans for Peace Now translated large parts of the speech here. It does not contain the claim about organ harvesting:
Because If there is something that scares us about the memory of the Holocaust, it is identifying nauseating processes that occurred in Europe in general and Germany in particular, 70, 80 and 90 years ago, and finding evidence of their presence here among us, today, in 2016.
For there is nothing easier than hating the alien. Nothing is easier and more simple than provoking anxiety and horror. Nothing is easier and simpler than brutalization, jadedness and self-righteousness.
The speech in its entirety (in Hebrew) can be seen in a video in this article, the first (actual) part of the quote is at about 0:45.
