I found this via Gaza mom Laila El-Haddad, her twitter feed:
“
anyone else see the vile ad on haaretz that calls for the expulsion of Palestinians to Jordan?? about 23 hours ago via web”
I went to Haaretz and after browsing a few pages eventally had the ad pop up once. I saved and attached a screen shot for you.

If you click on the add it goes to here.
Let Jordan be democratic and free, and let the Palestinian people accept upon themselves the full mantle and responsibility of democratic statehood in Jordan – without the destruction or diminishment of the state of Israel and without the physical transfer of any population, neither Jew nor Arab.
