Vehi She'amdah, a Passover prayer we say at the Seder Table.  Enjoy this live duet by Yaakov Shwekey and Yonatan Raizel in Caesaria.

The meaning of this song is like this:

And this is what stood for our forefathers and for us, that not one rose up against us to destroy us, but rather in every generation they rise up against us to destroy us, but the Holy One, Blessed is He, saves us from their hand.
