You're jumping the gun. You are required first to define "free" before you can say that the scriptures deny it. There will be no scriptures that deny free will if you want to claim there are no scriptures that speak of free will. Talk straight or not at all.
Just what do you think Philippians 2:13 is saying?
I agree. Add to that: "Define Will."
As alamo-girl has so ably point out, there are a host of if/then's throughout the bible; there are commandments; and there are instructions to "choose."
All of these indicate what is commonly referred to as free will.
The word "supralapsarian" (or infralapsarian) does not appear anyplace in scripture. And it doesn't have anywhere near the support of scripture as does "free will" and "prevenient grace."
Dortists will follow it "hook, line, and sinker."
Disengenuous dortists will even claim that grace doesn't exist prior to one's salvation. I'm betting that Calvin believed in some kind of common grace (prevenient), and that his writings will reveal the same.
Go figure.
