I've been missing Israel recently, especially Jerusalem. Psalm 137 comes to mind often:
By the rivers of Babylon we sat and wept
when we remembered Zion...
How can we sing the songs of the Lord
while in a foreign land?
If I forget you, O Jerusalem,
may my right hand forget its skill.
May my tongue cling to the roof of my mouth
if I do not remember you,
if I do not consider Jerusalem
my highest joy...
