It's interesting that the WeJew video comments note that "this song ("Shir HaMaalot" from Tehillim) is a virtual religious national anthem for the orange youth of Israel." The term "orange youth" refers to Israeli's who protested the 2005 Unilateral Disengagement Plan to remove all Israeli citizens from the Gaza strip and a number of surrounding settlements. The lyrics of Shir LaMa'alot are drawn from Psalm 121, A Song of Ascents, and contain the phrase..
I will lift up mine eyes unto the mountains: from whence shall my help come?Do not suffer thy foot to be moved from Gaza. Got it. A nice example of a political use of Jewish music and texts. But it's a good song regardless of your political leanings.
My help cometh from the LORD, who made heaven and earth.
He will not suffer thy foot to be moved; He that keepeth thee will not slumber. (emphasis added)
Yosef Karduner's Shir LaMa'alot
Update: Once again BlogInDm sets me straight. Yosef Karduner has a songbook, which includes Shir LaMa'alot, for sale at JewishJukebox.com.
