So before creation He foresaw something that He based His predestination on. Predestined is the action that took place, the effect of what He had foreseen in the future it’s a verb. Foreknowledge is what the action was based on or a result of, it’s a noun.
Your implication is that he did not know, except by looking forward in time, no?
Ok here’s a side question that might shed some light on this topic. Why did Jesus die for the sins of the whole world?
We've been through this how many times? What do you think "whole world" means there? Are you going to go with "simple reading" here, (unlike how you have to read other passages)? Or are you going to try to understand what the original readers would have understood it to be saying? Or better yet, what the writer most likely meant by it?
I keep seeing this argument you and others make, that foreknowledge simply means knowing the future (as a human wishes they could do —a human, temporal, construct). ONE WORD, used as you wish without Scriptural support, done so to smooth the way for the almighty notion, "free will", as though God's will is subject to the vagaries of human inclinations. To add to this argument, you have the self-deterministic construct "freewill", by which you apparently mean the ability to decide, not only apart from causation —that is, altogether spontaneously, as a small first cause— but dependent on the level of one's own goodness, apart from God. Your cornerstone is FREEWILL (which is not as such addressed in the Bible, and therefore, is a human construct) buttressed by one word ('foreknowledge') which you MUST take to mean only that God sees into the future as a human would if he could, and concerning which you ignore the Bible scholars. The rest of your arguments are attempts to defeat Calvinistic and Reformed tenets, and to get into other matters, in all appearance, frankly, as though to divert attention from the fact that the notion of self-deterministic freewill is skinny indeed.
"When Genesis 18:19 says "I have chosen him, " the verb is literally "I knew him." The same is true of Amos's description of Israel, "You only have I chosen of all the families of the earth" ( 3:2a ). Compare Paul's statement in Romans 11:2: "God did not reject his people, whom he foreknew." God's sovereign choice of Israel established a unique relationship with a particular people."

You even twisted what I said —that the Biblical term 'foreknowledge' is
causative— to mean that the foreknowledge causes the predestining, which is not what anyone means by 'foreknowledge being causative'. Frankly it doesn't even make sense for the Omniscient Creator of the Universe to need to see what we are going to do, in order to decide what to cause. The notion is illogical: to cause to happen what one already passively sees is going to happen.
I will attempt to describe, once again, the simple logic of causation. If something is true, or something exists, it is
caused, unless it is First Cause. If something is
caused, it is the result of at least one thing before it, which was also
caused unless it is First Cause. So if God (First Cause) sees something in the future, he caused it. You have not defeated this logic. You will continue to ignore it.
