So the provision in the US constitution for 'free speech' was not in harmony with Scripture ?
It would be more that Scripture doesn't provide us with material support or opposition to the provision of free speech under the US Constitution. Though a biblical argument can be made that human beings ought to be free subjects. More specifically: laws which injure human beings, in particularly the most vulnerable, are a product of wickedness.
If we take the biblical example of the Prophets of Israel, their ministries often involved speaking openly and loudly against the corruption of the powerful, including against wicked kings of Israel. The most potent example is Elijah and the corruption of King Ahab. The Prophets, of course, we understand spoke on behalf of God, therefore their words were right, just, and true; but as far as freedom is concerned, by speaking against the powerful they were in trouble with the corrupt powers that be. There was no right of free speech in the ancient world, kings determined what speech was acceptable and what speech was punishable, to speak against the king was a dangerous thing to do.
Now, you and I, we aren't prophets, but should we have the freedom to speak against the corruption of kings? If the king (or president, or prime minister, or any figure of authority) acts in such a way that we believe is in error or even wicked, is it preferable that there be laws which protect our ability to use our voice to speak against it? To be critical of the king? Or is it preferable that kings determine what is acceptable, and thus to speak out against corruption become treasonous?
Would the values and virtues which Scripture provides for us be closer in support to the right of people to speak against the evil and corruption of systems of power; or to the right of those systems of power to silence through threats of violence and imprisonment any who would speak against them?
The Scriptures provide no material support for the modern idea of free speech, because the modern idea of free speech simply did not exist in the ancient world when the words of the Bible were written. However, as it pertains to values, virtues, and ethical concerns of justice and righteousness, would the Bible be on the side of the vulnerable, or on the side of the powerful? On the side of speaking against power when it is corrupt, or on the side of silencing opposition to power?
In which case I believe a biblical argument can be made for safeguarding, as a right and freedom, the voice of ordinary people to speak out against perceived injustices and corruption. The Bible is pro-Elijah, rather than pro-Ahab.
