You can use the LUA interface "job.passes".
In the first pass, you store your value. For example:
local passdata = job.passes.define("mystuff") --I usually define this at 
the top of my script and reuse it.
passdata["somevalue"] = "hello world";

Then in the subsequent runs you can access
local lastpassdata = job.passes.getcollected("mystuff") --Same here...
