There is only one place in the Tanach that says "pray for Jerusalem." It does not say "pray for Israel," is says "pray for Jerusalem." It was written by King David and it can be found in the Psalms.

Pray for shalom in Jerusalem; may those who love you prosper. May shalom be within your ramparts, prosperity in your palaces. (Psa 122:6-7)

We will see here that Yeru-shalem is not a place, Yeru-shalem is a people. Those spiritually born who lead all within their gates with peace.
