You just gave a good demonstration on what this thread aims to show, and at the same time, answered your own question.
See how you just pulled a scripture, with the thought that you could make a solid argument in support of your own viewpoint, and when it was shot down by other scriptures, instead of giving pause, you ran with the idea that your way of seeing it, is still correct, rather than listen to reason?
Notice, you said, "it's not what you had in mind", so you read one text, held on to it, as, "Yes. Here is a text that supports view A, and destroys view B".
However, other texts, in the same Bible, show that you cannot just read one text, and believe that it supports your view... Notice - supports your view.
In other word, your view or interpretation, should not be the important thing here... nor is it, but the Bible's viewpoint is.
One should therefore read the Bible, to get the Bible's viewpoint... and how does the Bible give it's own viewpoint? We just saw it demonstrated.
Other texts confirm what it says, or deny what is thought.
This is what is meant by the Bible interprets, or speaks for itself.
So what you had in mind was denied.
That's the purpose of this thread, to show that it is not a matter of interpretation, and the Bible is not the fault. Rather, the problem lies, with men's ideas, which they want to force on the Bible, causing confusion in the minds of people who recognize the value in the Bible, or those who are seeking truthful answers.
This will continue as long as God allows man to follow his own will.
However, the Bible says, that soon he will remove all who want to follow their own will, and not submit to his will.
(Matthew 7:21-23)
21 “Not everyone saying to me, ‘Lord, Lord,’ will enter into the Kingdom of the heavens, but only the one doing the will of my Father who is in the heavens will. 22 Many will say to me in that day: ‘Lord, Lord, did we not prophesy in your name, and expel demons in your name, and perform many powerful works in your name?’ 23 And then I will declare to them: ‘I never knew you! Get away from me, you workers of lawlessness!’
(2 Thessalonians 1:6-8)
Recall that the Scribes and Pharisees protested that they knew also, but where did Jesus say that will get them?
Matthew. 23:13-15, 29-33
Protesting that one knows, and not listening to God's representatives is nothing new, according to the scriptural references in the OP. We saw the outcome of protesters.
There are two very, very good examples, I did not mention before.
Numbers 16 and
Numbers 12. God does not only use you they protested. Really?
The fact that there are people who protest to know... for their own will, does not annul, or make void the fact that God always chose human representatives, to convey his truths.
Are you here protesting that you know? Or are you asking with a view to searching for answers?
The short clear answer, as seen here, is that
God's mind had been revealed to all these people.
The division exists because persons insist on their own will, rather than accept the will of God... according to the Bible.
It is important we understand who divides, and with what goal in mind.
2 Corinthians 11
12 But what I am doing I will continue to do, in order to eliminate the pretext of those who are wanting a basis for being found equal to us in the things about which they boast.
13 For such men are false apostles, deceitful workers, disguising themselves as apostles of Christ.
14 And no wonder, for Satan himself keeps disguising himself as an angel of light.
15 It is therefore nothing extraordinary if his ministers also keep disguising themselves as ministers of righteousness. But their end will be according to their works.
